Set hasstatus => false on service under Debian Squeeze

Attempt two: Squeeze's monit init script doesn't support the status command, so running on Squeeze would result in Puppet attempting to restart Monit on each run. Wheezy hasstatus => true.

I don't have a RedHat box to test with, so I'm going to assume the right assumption has been made based on the existing `hasstatus => true` for them.
