The SSL SESSION files we were originally testing against use DHE and
SSLv3. AWS-LC happens to have no support for either and we have newer
possible alternatives available, so I've updated the respective
files to use ECDHE-RSA-AES256-SHA with TLS 1.1 and 1.2. I've verified
that these work as expected with all libcryptos we support.

There are also a few SSL session discrepencies in AWS-LC when
compared to OpenSSL.

1. AWS-LC has no support for internal session caching on the
   client-end.
2. AWS-LC supports internal session caching on the server, but
   SSL_get1_session does not return a resumable session with TLS 1.3
   in AWS-LC. Users have to use the SSL_CTX_sess_set_new_cb
   (ctx.session_new_cb in Ruby) to retrieve the resumable session
   ticket.
3. AWS-LC has no current support for external session caching in TLS
   1.3.
