vici: Fix connecting to socket in Python bindings on Windows

socket.connect() takes a single argument with the address that depends
on the address family, for TCP it's a tuple with IP and port.

Fixes: 00a75e332f ("vici: Create default TCP socket on Windows in Python bindings")
Closes strongswan/strongswan#1874
