Only run the simple image clean code if docuum is not running. It works
well enough in most cases, but has the drawbacks that it never deletes
"latest" images or images not matching "^osmocom-build", and may delete
images that are still being used (OS#5447). With the other tool, all
images are considered for removal, and the ones that have not been used
the longest time are removed first.

Do not only clean up dangling images, but also containers, volumes and
networks.

This script should be executed regularly on all build slaves that
have docker in order to discard unused images/layers. It would
be a good idea to call "fstrim /" afterwards in order to get more
SSD performance. However, the latter requires root access, and hence
cannot be called by the 'osmocom-build' user and thus jenkins.
Maybe we should install it as a cron job or systemd periodic timer job?
