Ciphers for SChannel

I saw that adding support for the --ciphers option in schannel was on the todo list:

Having spent some time trying to make this work, I found that the precise request of mapping in the OpenSSL ciphersuites was infeasible, and instead opted to pass algorithm identifiers ( through to schannel directly (as this was the most direct control that I could find for the library). I've attached a diff (taken against schannel.c in 7.59) that should serve the purpose, if this interpretation of the request is acceptable. Please me know how I may be of further assistance with this change.
