build: ignore unrelated workflow changes in slow Actions tests

test-asan and test-macos are very slow and tend to get backed up. While
I'm literally waiting hours right now for test-macos to finish so I can
land a PR, I'm opening this pull request to have it be skipped when
things other than its own workflow file are the only changes in the PR.
