Remove pass_filenames: false from pre-commit hook

[cbachhuber]

To make the vulture pre-commit hook work on the specific files specified by pre-commit and not on the entire repo, I need to override the config it as shown here, with pass_filenames: true. I argue that this is a saner default than pass_filenames: false, so let's remove it from vulture's pre-commit hook.
