[PATCH bpf-next 0/4] selftests/bpf: add a new runner for bpftool tests

["Alexis Lothoré (eBPF Foundation)" <alexis.lothore@bootlin.com>]

Hello,
this series is part of the larger effort aiming to convert all
standalone tests to the CI runners so that they are properly executed on
patches submission.

Some of those tests are validating bpftool behavior(test_bpftool_map.sh,
test_bpftool_metadata.sh, test_bpftool_synctypes.py, test_bpftool.py...)
and so they do not integrate well in test_progs. This series proposes to
introduce a new runner to support those tests. This new runner is
heavily inspired from test_progs, with slightly less features.

- First commit move the assert macros exposed by test_progs into a
  shared header so that they can be used by the new runner
- Second commit introduces the new runner, as well as a first test
- Third commit adds a second test
- Fourth commit drops the legacy scripts corresponding to those new
  tests

The series only adds the runner, but it is not enough to have it running
in CI. The github actions need to be updated both in [1] and [2], and I
am not sure how it si supposed to be contributed (the part needed in [1]
must likely be integrated in the commit that is systematically brought
on top of the bpf-next_base branch). Still, an example of test_bpftool
run can be found in [3], in which I have forked and updated the needed
Github actions ([4])
