fix: Another attempt at fixing git-clean permission issues (chown -R)

We're still seeing the issue. Remove the safe-directory stuff (which might
have worked if we dropped the `become_user`, but was probably more
complicated than necessary) and instead just `chown -R` the repo before
doing the clean. Hopefully that does it.
