mgcp_client: Make MGCP_CLIENT_LOCAL_ADDR_DEFAULT IPv6 compatible

If "0.0.0.0", the default, is passed together with an IPv6 configured
address (ex: "mgw remote-ip ::1") in VTY, socket creation will fail due
to address version mismatch (because getaddrinfo() returns only an IPv4
address in the local result set).
If instead NULL is passed, then 2 entries are returned, one in IPv4 and
one in IPv6, and osmo_sock_init2 is smart enough to take one or another
when passed AF_UNSPEC.
