selftests/bpf: skip verifier tests for unsupported program types
in upstream stable v5.0.7. It would require
commit 1bf4b05810fe38c5f09973295e8d4234a4fd5d87

Date: Thu Jan 17 15:27:53 2019 +0000
tools: bpftool: add probes for eBPF program types
backported (not tried yet how hard that is) which has not been done
upstream stable (at least not up to v5.0.15). Likely nobody tried yet.
Unless we have something else that makes a re-spin a must, I would
hesitate to initiate a full round for the test being broken. Do we have
a way to work around this? And we should work on the resolution (either
additional backport or revert) to be included in the next cycle.

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
5.0.0-16 Disco + 5.0.0-16 source code - Failed
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.
