Make instantiated mapper services oneshot

The systemd issue which prevented use of Restart= policy in oneshot
services has been fixed. Therefore, mapper-wait@ and
mapper-subtree-remove@ services can be cleaned up and simplified.

Tested:
1. Created a simple test.service which has Wants/After dependency on
   mapper-wait@-some-object.service, and just echos "TEST" to journal.
2. systemctl start test; verify it hangs since object doesn't exist yet
3. Start service which creates /some/object; verify test.service is
   started.
4. systemctl restart test; verify it starts immediately
5. Stop service which publishes /some/object
6. systemctl restart test; verify it starts immediately, since
   mapper-wait@-some-object is still active, even though the object is
   gone.
