networkd: don't filter on udev tags

This removed the requirement for devices to be tagged with
'systemd-networkd' before they will be visible to networkd.

Still, as by default we don't ship any .network files, network
devices will simply be tracked, but not touched, unless the
admin configures things explicitly.
