networkd: turn on LLDP reception by default, in "routers-only" mode 

This way "networkctl status" becomes a bit more useful by default, as router
information is just visible, without any further configuration.

LLDP reception is fully passive and relatively low simple and low traffic,
hence this should be safe to enable by default.
