 Bug 16138: Restart plack when rotating logfiles

On log rotation Starman/Plack keeps failing (Auth.pm related problems) due to
permission issues:

Could not compile /usr/share/koha/opac/cgi-bin/opac/opac-search.pl: Can't locate Authen/CAS/Client/Response/Failure.pm

As we do with zebra daemons, starman should be restarted as it doesn't handle log file rotation
gracefully[1].

I'm not sure how to reproduce it on a dev environment.
