Add logrotate support for *.log files in /run mounts of apps

logrotate config files may contain arbitrary commands which are
exectued as root, thus the config files have to be owned by root.
This is the reason we need the sudo scripts :-/

To test the generated scripts, just run:
$ logrotate /etc/logrotate.conf -v

Fixes #396
