[PATCH 5.13 478/800] selftests/bpf: Whitelist test_progs.h from .gitignore

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

From: Daniel Xu <dxu@xxxxxxxxx>

[ Upstream commit 809ed84de8b3f2fd7b1d06efb94bf98fd318a7d7 ]

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
