Merge branch 'selftests/bpf: Improve the usability of test_progs'

Yucong Sun says:

====================

This short series adds two new switches to test_progs, "-a" and "-d",
adding support for both exact string matching, as well as '*' wildcards.
It also cleans up the output to make it possible to generate
allowlist/denylist using common cli tools.
