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.
