Bug #11739: OpenSSL::SSL::SSLServer doesn't negotiate ECDHE-* ciphersuites

----------------------------------------
I'm trying to configure an instance of OpenSSL::SSL::SSLServer that supports Elliptic curve DiffieHellman. No matter what combination of Rubyand OpenSSL versions I try the negotiation with the client fails. 

Proof of concept:
https://gist.github.com/brandonweeks/e26414cc1e9eea9453a8

Then run:
>openssl s_client -connect localhost:8443

Also attaching a pcap file of the failed handshake.
