Adjust IP rules to accommodate UID-based firewall

* No default implicit network rule. We have UID-based implicit rules.
* Can only use VPN fallthrough with system permission. It is not
  UID-based, and other rules fulfill our needs.
* Binding to output interfaces arbitrarily requires system permission.
  Other rules cover this where it should be allowed for UIDs.
* Require system permission for RULE_PRIORITY_DEFAULT_NETWORK rule.
  Default network access is already allowed for UIDs permitted on the
  network via RULE_PRIORITY_UID_DEFAULT_NETWORK rules.
