Subject: [spice-server] ssl: Allow to use ECDH ciphers with OpenSSL 1.0
Without an explicit call to SSL_CTX_set_ecdh_auto(reds->ctx, 1), OpenSSL
1.0 (still used by el7) would not use ECDH ciphers (this is now
automatic with OpenSSL 1.1.0). This commit adds this missing call. It's
based on a suggestion from David Jasa
