src: rename CONNECTION provider to SSLCONNECTION

Currently the async provider type CONNECTION is used in node_crypto.h
and it might be clearer if it was named SSLCONNECTION as suggested by
addaleax.

This commit renames only the provider type as I was not sure if it was
alright to change the class Connection as well.
