Implemented FR #53447 (Cannot disable SessionTicket extension for servers that

do not support it).

I haven't written a test due to the need for such a test to have a HTTPS server
available which mishandles SessionTicket requests; it's likely that server
administrators will gradually fix this either intentionally or through OpenSSL
upgrades. That said, if there's a great clamoring for a test, I'll work one up.
