change localip is6 flag based on destination ip
By default, the localip flag is initialized with
the is6 flag set to 0. The only time the flag is
changed to 1 is when a user specifies a local IPv6
address to use.
Because of this, socket_tcp46 always creates an IPv4
socket.
This patch corrects that - if the user hasn't specified
a local address, then the local 'is6' flag is updated
to match the destination 'is6' flag.
