[PATCH] gitignore: Don't ignore 'tags' directory

[Li Zhijian]

LKP reported warnings [1] regarding files being ignored:
   tools/testing/selftests/arm64/tags/.gitignore: warning: ignored by one of the .gitignore files
   tools/testing/selftests/arm64/tags/Makefile: warning: ignored by one of the .gitignore files
   tools/testing/selftests/arm64/tags/tags_test.c: warning: ignored by one of the .gitignore files

These warnings were generated by ./scripts/misc-check. Although these files
are tracked by Git and the warnings are false positives, adjusting the
.gitignore entries will prevent these warnings and ensure a smoother script
execution.
