rgmanager: Fix dependency issue related to ordering (RHEL5)
 
If you ordered two services the opposite way in cluster.conf
('b' first, which depends on 'a'), then rgmanager would fail
over 'b' despite the fact that 'a' was not running yet - this
is because the state of 'a' was not set to 'stopped' - so we
need to check for a node-death event in move_or_start().
