Only lint files in the working copy with arc lint --everything.

Summary: Fixes T5442. `arc lint --everything` currently uses a `FileFinder` to discover paths for linting. A consequence of this is that files that are ignored or otherwise excluded from version control are linted.

Test Plan: Ran `arc lint --everything` in rPHU and noticed that I wasn't prompted to add a trailing newline to `src/.phutil_module_cache`.
