[PATCH bpf] bpf: selftests: Whitelist test_progs.h from .gitignore

[Daniel Xu <dxu@xxxxxxxxx>]

Somehow test_progs.h was being included by the existing rule:

    /test_progs*

This is bad because:

    1) test_progs.h is a checked in file
    2) grep-like tools like ripgrep[0] respect gitignore and
       test_progs.h was being hidden from searches

[0]: https://github.com/BurntSushi/ripgrep

Fixes: 74b5a5968fe8 ("selftests/bpf: Replace test_progs and test_maps w/
general rule")
