Add supporting changes for `Add limited sandbox capability to "make check"`

Non-tests/... changes:
- Add HAS_TESTS= to Makefiles with libraries and programs to enable iteration
and propagate the appropriate environment down to *.test.mk.

tests/... changes:
- Add appropriate support Makefile.inc's to set HAS_TESTS in a minimal manner,
since tests/... is a special subdirectory tree compared to the others.

Start writing up some basic feature tests for procstat

These tests query a running process for information related to the -b,
-c, -e, and -f flags; the -f testcase is largely stubbed out, pending
additional work to determine a good, deterministic descriptor.

Core file test support is coming soon--it requires a bit more effort
due to the fact that:
- coredumps can be disabled (kern.coredump=0).
- corefiles can be put in different directories than the current
directory, or be named something other than `<prog>.core`
(`kern.corefile`).
