mgw: Introduce VTY cmd 'rtp bind-ip-v6' command
This commit allows for fully IPv6 systems to work fine. However, if a
remote endpoint still wants to use IPv4, it will fail since at this
point osmo-mgw still doesn't re-bind the local end of the connection to
an IPv4 after having initially bound it to an IPv6 one. This kind of
scenarios get fixed in next commits.
TODO: really bind the socket if a different IP address is requested.
