nixos/wireguard: add test

After working on the last wireguard bump (#57534), we figured that it's
probably a good idea to have a basic test which confirms that a simple
VPN with wireguard still works.

This test starts two peers with a `wg0` network interface and adds a v4
and a v6 route that goes through `wg0`.
