Some installed Python scripts need to be executable

During mhrlpr fixmsg at least these two scripts needs to be marked as executable (chmod +x) otherwise it fails.

/usr/lib/python3.12/site-packages/mrhlpr/data/msg_filter_add_commit_id.py and /usr/lib/python3.12/site-packages/mrhlpr/data/msg_filter_add_label.py
