[PATCH] monit: Some fixes for 'monitrc'

Just cosmetics:
Removed all trailing spaces - there were a few...

Activated 'monit' start delay:
I activated this option to avoid running into a race condition while started through
'/etc/init.d/monit start'.

As mentioned in 'monit' manual:
"...if a service is slow to start, Monit can assume that the service is not running
and possibly try to start it [again] and raise an alert, while, in fact the service
is already about to start or already in its startup sequence."

This happened here during testing with (e.g.) Clamav.
