python/machine: use connect-based interface for existing sockets

Browse source 
Instead of using accept() with sockets (which uses open_with_socket()),
use calls to connect() to utilize existing sockets instead. A benefit of
this is more robust error handling already present within the connect()
call that isn't present in open_with_socket().
