Change the precendence of the configured IPv6 gateway address so it has higher precedence than routers found through discovery.
This provides more flexibility because not configuring the gateway address provides the original behavior so functionality can be turned on/off. The other way it depends if there is a IPv6 router on the network or not.
lwip also currently does not check the prefixes the router is advertising so it is safer to use a configured default route if one is provided.
lwip did not have IPv6 gateway support to begin with, so this change is fixing code I previously added...
