This patch adds explicit requirements for virtual network address services to run after and only when udevd service is running. Also depend on virt netdev creation service instead of device.

Tested by adding following to the defenestrate configuration:

networking.greTunnels."testGreTun" = {
      dev = "enp1s0";
      remote = "103.206.98.8";
      local = "192.168.122.75";
      ttl = 255;
      type = "tun";
    };
    networking.interfaces."testGreTun" = {
      ipv4.addresses = [
        {
          address = "10.47.8.1";
          prefixLength = 31;
        }
      ];
      ipv4.routes = [
        {
          address = "0.0.0.0";
          prefixLength = 0;
          via = "10.47.8.0";
          options.table = "3";
        }
      ];
    };
    systemd.services."network-addresses-testGreTun" = {
      after = pkgs.lib.mkOverride 1 [ "network-pre.target" "testGreTun-netdev.service" "systemd-udevd.service"  ];
      requires = [ "systemd-udevd.service"  ];
  };

and in flake.nix switching inputs.nixpkgs.url = github:NixOS/nixpkgs/ between 1dab772dd4a68a7bba5d9460685547ff8e17d899 and fddbd3e9800c214f83674791a883716c168a8539 back and forth.
Also checked that changing the interface parameters happens without errors.
