nixos/lxc/container: fix useDhcp with veth

Browse Source 
https://github.com/NixOS/nixpkgs/pull/347283 changed the default to
exclude non-physical network Kind, but that unfortunately also includes
`veth` which LXC uses for its network interfaces. Re-enable that
functionality so users can use networkd with useDHCP.
