Don't execute final_action if failure_action terminates the system

Browse Source 
If failure_action is shutdown/reboot/halt, final_action is pointless as
the system will be already stopping. And if final_action is different
from failure_action, it will trigger a systemd race problem and cause
unexpected behavior to occur.

So let the error handler stop and exit after performing failure_action
successfully if failure_action is one of shutdown/reboot/halt.
This way, final_action will not be executed.
