model: Change NetDeviceFace into NetDeviceLinkService to match NFD 0.4+ Face model
ndnSIM (for now) intentionally uses LinkService instead of Transport for
optimization purposes and in order to preserve ns3::Packet Tags. This
may be fixed in the future when there is a different mechanism to
propagate ns3 Tags or Tags are no longer necessary.
