Bug description:
This test will failed to build on 5.0.0-16 Disco.
5.0.0-16 Disco + 5.0.0-15 source code - build OK

Bisect shows this one e38969c9 (selftests/bpf: skip verifier tests for
unsupported program types) in our tree is the cause (upstream commit:
8184d44c)
Which uses a "recently introduced bpf_probe_prog_type()" to skip test.
And we don't have it implemented.
