ggsn: Use osmo_netdev_addaddr() libosmocore API

Browse Source 
This allows dropping a lot of duplicated code.
While at it, drop references to non-linux systems, which are not
maintained anymore.
Param "dstaddr" was not used anywhere in the old APIs, so it can also be
dropped.
Param "tun->routes" was also used in BSD code, so it can also be
dropped.
