nixos/qemu-vm: fix running VM with QEMU_NET_OPTS 
I realized quite recently that running a test VM - as documented in the
manual - like

    QEMU_NET_OPTS='hostfwd=tcp::8080-:80'  ./result/bin/nixos-run-vms

doesn't work anymore on `master`. After bisecting I realized that the
introduction of a forward-port option[1] is the problem since it adds a
trailing comma even if no forwarding options are specified via
`virtualisation.forwardPorts`. In that case, the networking options
would look like `-netdev user,id=user.0,,hostfwd=tcp::8080-:80' which
confused QEMU and thus the VM refused to start.

Now, the trailing comma is only added if additional port forwards are
specified declaratively.
