Subject: [PATCH bpf-next v2 0/4] selftests/bpf: migrate a few bpftool
 testing scripts

Hello,
this is the v2 for some bpftool tests conversion. This new version drops
a large part of the previous version, as it eventually integrates the
converted tests into test_progs rather than into a new dedicated runner.
The new tests however are almost identical to those in v1, as the
dropped test_bpftool runner was exposing the same kind of features as
those in test_progs.

- First commit is just a small cleanup, reordering files in the
  selftests Makefile
- Second commit introduces a few dedicated helpers to execute bpftool
  commands, with or without retrieving the generated stdout output
- Third commit integrates test_bpftool_metadata.sh into test_progs
- Fourth commit integrates test_bpftool_map.sh into test_progs

Changes in v2:
- drop standalone runner in favor of test_progs
- Link to v1: https://lore.kernel.org/r/20260114-bpftool-tests-v1-0-cfab1cc9beaf@bootlin.com
