dns: T5144: Explicitly override ddclient global options for reliability

- For option 'web', ddclient defaults to 'dyndns' which doesn't support
  ssl. This results ddclient process lockup till connection to
  checkip.dyndns.org:443 times out.
- For option 'use', ddclient defaults 'ip'. This results in confusing
  message "WARNING:  '' is not a valid IPv4 or IPv6 address" in log.
