service: a cgroup empty notification isn't reason enough to go down
The processes associated with a service are not just the ones in its
cgroup, but also the control and main processes, which might possibly
live outside of it, for example if they transitioned into their own
cgroups because they registered a PAM session of their own. Hence, if we
get a cgroup empty notification always check if the main PID is still
around before taking action too eagerly.
Fixes: #6045
