nixos/network-interfaces-systemd: do not ignore /0 gateway routes
While it might seem odd, 0.0.0.0/0 or ::/0 gateways are valid and commonly used on point-to-point links (e.g. a wireguard tunnel) to indicate that all traffic needs to be sent to a given interface. systemd-networkd actually documents this as a valid configuration in its man pages [1]. Tested to do the right thing in one of my NixOS containers using a Wireguard tunnel as its default route.
