automount: rework propagation between automount and mount units

Port the progagation logic to the generic Unit->trigger_notify() callback logic
in the unit vtable, that is called for a unit not only when the triggered unit
of it changes state but also when a job for that unit finishes. This, firstly
allows us to make the code a bit cleaner and more generic, but more
importantly, allows us to notice correctly when a mount job fails, and
propagate that back to autofs client processes.

Fixes: #2181
