selftests/bpf: Rename libarena malloc/free methods
The s390 architecture uses the token "free" for an enum, conflicting
with the malloc/free definitions. Rename the calls to arena_malloc and
arena_free instead to prevent collisions.

selftests/bpf: Add buddy allocator for libarena
Add a byte-oriented buddy allocator for libarena. The buddy
allocator provides an alloc/free interface for small arena allocations
ranging from 16 bytes to 512 KiB. Lower allocations values are rounded
up to 16 bytes. The buddy allocator does not handle larger allocations
that can instead use the existing bpf_arena_{alloc, free}_pages() kfunc.

selftests/bpf: Add basic libarena scaffolding
Add initial code and a Makefile for an arena-based BPF library. Modules
can be added just by including the source file in the library's src/
subdirectory. Future commits will introduce the library code itself.
The code includes workarounds that are removed in subsequent patches
that ensure bisectability.
