Are OpenSSL crypto policies supported upstream? If so, I think we should
just rely on them and leave this workaround for downstreams if they want
it. Also, what would we do if spice changed its TLS code to use another
library, wouldn't it force us to translate the parameters from OpenSSL
to the other library if this happens and this code is merged upstream?
