RFR: 8359978: Test javax/net/ssl/SSLSocket/Tls13PacketSize.java failed again with java.net.SocketException: An established connection was aborted by the software in your host machine

[Matthew Donovan]

This PR updates the TLS13PacketSize test so the client-side of the connection also reads any available data from the socket before closing. I have been unable to recreate the SocketException after 1000s of test iterations.
