David Benjamin ee1ed1d380 Fix the names of older ciphers.
The names of these ciphers have an "SSL_" prefix, but the RFC names use
"TLS_":
https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-4

This dates back to these ciphers being originally defined in SSLv3. As
SSLv3 is on its way out anyway and this is a new set of APIs,
consistently use the TLS names.
