test-network: also save the current state of socket units for resolved and stop them

Silence the following waring:
```
Stopping 'systemd-resolved.service', but its triggering units are still active:
systemd-resolved-varlink.socket, systemd-resolved-monitor.socket
```

Follow-up for 0fa188307b1c286e7b86201b1cfb91014b970092.
