David Gibson 5e93bcd8bf test: Adjust misplaced sleeps in two_guests code
Most of our transfer tests using socat use 'sleep' waaiting for the server
side to be ready before starting the client.  However in two_guests/basic
the sleep is in the wrong place: rather than being between starting the
server and starting the client, it's after waiting for the server to
complete.  This causes occasional hangs when the client runs before the
server is ready - in that case the receiving guest sends an RST, which we
don't (currently) propagate back to the sender.
