[PATCH] vfio: selftests: Fix .gitignore for already tracked files

[David Matlack]

Fix the rules in tools/testing/selftests/vfio/.gitignore to not ignore
some already tracked files (.gitignore, Makefile, lib/libvfio.mk).

This change should be a no-op, since these files are already tracked by git and
thus git will not ignore updates to them even though they match the ignore
rules in the VFIO selftests .gitignore file.

However, they do generate warnings with W=1, as reported by the kernel test
robot.

  $ KBUILD_EXTRA_WARN=1 scripts/misc-check
  tools/testing/selftests/vfio/.gitignore: warning: ignored by one of the .gitignore files
  tools/testing/selftests/vfio/Makefile: warning: ignored by one of the .gitignore files
  tools/testing/selftests/vfio/lib/libvfio.mk: warning: ignored by one of the .gitignore files

Fix this by explicitly un-ignoring the tracked files.

Fixes: 292e9ee22b0a ("selftests: Create tools/testing/selftests/vfio")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202508280918.rFRyiLEU-lkp@intel.com/

Note, this is on top of the vfio/next branch so I'm not sure if the hash
in the fixes tag is guaranteed to be stable. It might be simpler to
squash this into commit 292e9ee22b0a ("selftests: Create
tools/testing/selftests/vfio") before sending the pull request to Linus.

Applied to vfio next branch for v6.18.  Let's consider the commit
hashes sufficiently stable for now.  In the off chance that I need to
back something out, I can fix them.  I think it's useful for the log
to have the fixes separate, as evidenced by being able to reference
Sean's similar fix.  Thanks,

Alex
