/var/run/ is only writable by root so Monit will fail to create
the necessary subdirectory for the jenkins pid file since we run it
as the 'jenkin' user. We add another entry to the monit configuration
file to check the presence and the permissions of that directory before
we try to start the jenkins slave.
