tools, bpftool: Correctly evaluate $(BUILD_BPF_SKELS) in Makefile

tools, bpftool: Correctly evaluate $(BUILD_BPF_SKELS) in Makefile
Currently, if the clang-bpf-co-re feature is not available, the build fails with e.g.
CC prog.o prog.c:1462:10: fatal error: profiler.skel.h: No such file or directory 1462 | #include "profiler.skel.h" | ^~~~~~~~~~~~~~~~~
This is due to the fact that the BPFTOOL_WITHOUT_SKELETONS macro is not defined, despite BUILD_BPF_SKELS not being set. Fix this by correctly evaluating $(BUILD_BPF_SKELS) when deciding on whether to add -DBPFTOOL_WITHOUT_SKELETONS to CFLAGS.

Merge branch 'bpftool-show-pid'
Andrii Nakryiko says:
==================== This patch set implements libbpf support for a second kind of special externs, kernel symbols, in addition to existing Kconfig externs.
Right now, only untyped (const void) externs are supported, which, in C language, allow only to take their address. In the future, with kernel BTF getting type info about its own global and per-cpu variables, libbpf will extend this support with BTF type info, which will allow to also directly access variable's contents and follow its internal pointers, similarly to how it's possible today in fentry/fexit programs.
As a first practical use of this functionality, bpftool gained ability to show PIDs of processes that have open file descriptors for BPF map/program/link/BTF object. It relies on iter/task_file BPF iterator program to extract this information efficiently.
There was a bunch of bpftool refactoring (especially Makefile) necessary to generalize bpftool's internal BPF program use. This includes generalization of BPF skeletons support, addition of a vmlinux.h generation, extracting and building minimal subset of bpftool for bootstrapping.
v2->v3: - fix sec_btf_id check (Hao);
v1->v2: - docs fixes (Quentin); - dual GPL/BSD license for pid_inter.bpf.c (Quentin); - NULL-init kcfg_data (Hao Luo);
rfc->v1: - show pids, if supported by kernel, always (Alexei); - switched iter output to binary to support showing process names; - update man pages; - fix few minor bugs in libbpf w.r.t. extern iteration. ====================

tools/bpftool: Show info for processes holding BPF map/prog/link/btf FDs
Add bpf_iter-based way to find all the processes that hold open FDs against BPF object (map, prog, link, btf). bpftool always attempts to discover this, but will silently give up if kernel doesn't yet support bpf_iter BPF programs. Process name and PID are emitted for each process (task group).

tools/bpftool: Minimize bootstrap bpftool
Build minimal "bootstrap mode" bpftool to enable skeleton (and, later, vmlinux.h generation), instead of building almost complete, but slightly different (w/o skeletons, etc) bpftool to bootstrap complete bpftool build.
Current approach doesn't scale well (engineering-wise) when adding more BPF programs to bpftool and other complicated functionality, as it requires constant adjusting of the code to work in both bootstrapped mode and normal mode.
So it's better to build only minimal bpftool version that supports only BPF skeleton code generation and BTF-to-C conversion. Thankfully, this is quite easy to accomplish due to internal modularity of bpftool commands. This will also allow to keep adding new functionality to bpftool in general, without the need to care about bootstrap mode for those new parts of bpftool.

tools: bpftool: Allow unprivileged users to probe features
There is demand for a way to identify what BPF helper functions are available to unprivileged users. To do so, allow unprivileged users to run "bpftool feature probe" to list BPF-related features. This will only show features accessible to those users, and may not reflect the full list of features available (to administrators) on the system.
To avoid the case where bpftool is inadvertently run as non-root and would list only a subset of the features supported by the system when it would be expected to list all of them, running as unprivileged is gated behind the "unprivileged" keyword passed to the command line. When used by a privileged user, this keyword allows to drop the CAP_SYS_ADMIN and to list the features available to unprivileged users. Note that this addsd a dependency on libpcap for compiling bpftool.
Note that there is no particular reason why the probes were restricted to root, other than the fact I did not need them for unprivileged and did not bother with the additional checks at the time probes were added.
