Make sure we trigger retransmits in DTLS testing
During a DTLS handshake we may need to periodically handle timeouts in the DTLS timer to ensure retransmits due to lost packets are performed. However, one peer will always complete a handshake before the other. The DTLS timer stops once the handshake has finished so any handshake messages lost after that point will not automatically get retransmitted simply by calling DTLSv1_handle_timeout(). However attempting an SSL_read implies a DTLSv1_handle_timeout() and additionally will process records received from the peer. If those records are themselves retransmits then we know that the peer has not completed its handshake yet and a retransmit of our final flight automatically occurs.
