ttcn3-mgw: Set osmux bind-ip(-v6) VTY configs

Until now we forgot to properly configure the osmux socket local ip, but
that was fine because 0.0.0.0 was taken as a default.
With addition of IPv6, this changed, and the socket is not bound unless
an IP address is set (to allow conditional use of IPv4, IPv6 or both).
