nixos/networkd: Make activatible through dbus and netlink

Browse source 
With this systemd buffers netlink messages in early boot from the kernel
itself; and passes them on to networkd for processing once it's started.
Makes sure no routing messages are missed.

Also makes an alias so that dbus can activate this unit. Upstream has
this too.
