`check-useless-excludes` meta hook doesn't seem to work well with broken symlinks
Repro steps
1. Add a submodule
2. Add a symlink to somewhere inside this submodule
3. Use `check-symlinks`
4. Deinit submodule (to simulate the case when people clone without `--recursive`)
4. Notice that it now complains about the symlink created on 2
5. Add an exclude entry with the path to that symlink
6. Use `check-useless-excludes`
7. Notice that it complains that the added exclude entry doesn't apply.

For a working example, check out https://github.com/pkoch/test-check-useless-excludes (without `--recursive`, or run `git submodule deinit --all`) and run `pre-commit run --all`.
