[interfaces-config.sh] Force lo interface down (#4149)

Browse Source 
Force "lo" interface down in interfaces-config.sh to prevent interface-config.service from failing with the following error:

```
-- The result is failed.
systemd[1]: networking.service: Unit entered failed state.
systemd[1]: networking.service: Failed with result 'exit-code'.
interfaces-config.sh[29232]: Job for networking.service failed because the control process exited with error code.
interfaces-config.sh[29232]: See "systemctl status networking.service" and "journalctl -xe" for details.
interfaces-config.sh[29232]: ifdown: interface lo not configured
interfaces-config.sh[29232]: RTNETLINK answers: File exists
interfaces-config.sh[29232]: ifup: failed to bring up lo
systemd[1]: interfaces-config.service: Main process exited, code=exited, status=1/FAILURE
systemd[1]: Failed to start Update interfaces configuration.
-- Subject: Unit interfaces-config.service has failed
```

Failure to bring down the interface will result in a failure to subsequently bring the interface back up.
