Clean up /tmp when checking mirrors
Sometimes the cron job that checks mirrors fails and leaves leftovers in
/tmp/check-mirrors*. This may cause the next check to fail because of lack of disk space.
We have to:
- ensure the cronjob that runs check-mirrors cleans up if check-mirrors fails to do it itself
- ensure systemd tmpfiles is configured to garbage collect such leftovers after a little while
