[BUG 55275] Prevent category_redirect.py from doing cosmetic changes

category_redirect touches category to clean them. Thus it is a good
idea to keep them off from doing cosmetic changes by placing it to
the cosmetic_changes_deny_script list.

cosmetic_changes_deny_script is a list of scripts for which cosmetic changes are disabled.

Some parts where synchronized with compat.
