CA-234893: sm-multipath.service goes inactive after SM RPM upgrade

After an sm rpm upgrade, sm-multipath service was deactivated and
not re-activated, leading to problems after a host reboot.

The fix is composed in two parts:
1) deactivate sm-multipath service only on full uninstall
2) add a posttrans hook to activate sm-multipath after
   an upgrade (mainly needed as workaround for when we
   upgrade from a version without this fix)
