First, I think we should make sure CURLINFO_TLS_SESSION return the backend
define for them all, independently of if we support the 'internals' or not.
I'll work up a fix for that.

But this of course won't help anyone using existing libcurl versions.

For existing libcurl versions, you can use curl_version_info() and check the
'ssl_version' field of the returned struct. That's unfortunately a string so
it isn't as suitable for comparisons but I think this is the best we can offer
right now.
