fix(network-manager): add "After" dependency on dbus.service

During shutdown, there is no ordering dependency between the nm-initrd service
and the D-Bus daemon, and so the latter can be stopped before. This causes
issues to NetworkManager, especially when team interfaces are present because
NM will see teamd dropping from the bus and will try to reactivate the
connection.

Add a "After" dependency to make sure the D-Bus daemon is stopped after NM on
shutdown.
