Add test for SSL_set_session_ticket_ext
The function SSL_set_session_ticket_ext sets the ticket data to be sent in the ClientHello. This is useful for EAP-FAST. This commit adds a test to ensure that when this function is called the expected ticket data actually appears in the ClientHello. Reviewed-by: Viktor Dukhovni <viktor@openssl.org>
