Remove unhelpful "Check for whitespace in front of *'s" from .git-hooks

It was added with 60f200ca "git-hooks: Copy them
from the build repo", but I don't see its purpose, and it caused trouble for me
now when trying to commit <https://gerrit.libreoffice.org/67672> "Merge in
Flatpak improvements".
