Fix daily cleanup of Puppet reports
Originally created by @intrigeri on #11468 (Redmine)
It seems that it doesn’t: we still get disk space issues on puppet-git.lizard. I wonder if the cronjob actually runs, or if we merely survive because we run the script by hand from time to time. FTR, after running it, I see 1.1 GB of reports left. So in the worst case we should in theory be storing ~2.2GB of reports just before the cleanup is done. This doesn’t really match what Icinga is telling us, so something must be wrong.
