nixos/networkd: add MACVTAP= option for networks

Example 10. of man page of systemd.network(5) shows:
```

       Example 10. MacVTap

       This brings up a network interface "macvtap-test" and attaches it to "enp0s25".

           # /usr/lib/systemd/network/25-macvtap.network
           [Match]
           Name=enp0s25

           [Network]
           MACVTAP=macvtap-test
```

Which is a MACVTAP example and is currently unsupported in NixOS.
This is useful for people using "modern" technologies with virtual machines.
