kselftests-bpf: add kernel BPF tests
Build and package kernel self-tests used for BPF testing, program and JIT development. This package, together with the existing 'kmod-bpf-test', was extensively used for past upstream Linux JIT submissions [1]. Currently this includes only 'test_verifier'; building 'test_progs' will fail due to known endian limitations with bpftool skeletons. [1]:https://lore.kernel.org/bpf/cover.1633392335.git.Tony.Ambardar@gmail.com Signed-off-by: Tony Ambardar <itugrok@yahoo.com> (cherry picked from commit 3886ea9b87c416c080078603fedea95bcc144442)
