Subject: [PATCH] automount: handle state changes of the corresponding mount
 unit correctly

The expire timeout must be started/stopped if the corresponding mount unit
changes its state, e.g. it is started via local-fs.target or stopped by a
manual umount.

(cherry picked from commit 3dbadf9ef96e76f1bc472660ba5435dc0fa27a66)

Resolves: #1596241
