scripts: check_compliance: un-ignore diff and patch for CheckPatch

Un-ignore diff and patch files for CheckPatch.

This was originally added to avoid throwing false-positives when diff
and patch files were actually in the repo, since it would incorrectly
try to perform code-formatting checks on those files instead of on
the content of the commit.
