tools: testing: vsock: Test when server is bound but not listening
Whenever the server side of vsock is binding to the socket, but not listening yet, we expect the behavior from the client to be identical to what happens when the server is not even started. This new test runs the server side so that it binds to the socket without ever listening to it. The client side will try to connect and should receive an ECONNRESET error. This new test provides a way to validate the previously introduced patch for making sure the server side will always answer with a RST packet in case the client requested a new connection.
