CI: Fix exclude patterns with `git ls-files`

Follow-up to #55785.

In `black_format.sh`, the `--exclude` switch was wrongly used. It's a misnomer
that only excludes _untracked_ files, arcane pathspec patterns should instead
be used to exclude _tracked_ files.

Using this newfound knowledge, we can also simplify the other scripts.
