[Spice-devel] [spice-server] ssl: Allow to use ECDH ciphers with OpenSSL 1.0

[Christophe Fergeau]

Without an explicit call to SSL_CTX_set_ecdh_auto(reds->ctx, 1), OpenSSL
1.0 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
