[FIX for 14/16] multipath.rules: set job properties for systemd-run correctly

[Martin Wilck <mwilck@suse.com>]

The default dependencies must be turned off for both the timer and
the service unit, otherwise systemd-run will wait for sysinit.target.

Moreover, fix these bugs:
 - never run the logic if DM_MULTIPATH_DEVICE_PATH!=2
 - reset DM_MULTIPATH_DEVICE_PATH to "" on timer expiry
