Remove relative paths for clang-tidy annotations (pytorch#62004)

Summary:
Pull Request resolved: pytorch#62004

Some of the files checked by clang tidy are compiled from a sibling directory, so the files all start with something like `../torch`. This ends up messing with `translate_annotations.py` which runs from the repo root. This fixes it by chopping off any relative paths in the clang tidy output.
