Temporarily restore SHA256 and SHA384 cipher suite aliases.

Browse Source 
https://boringssl-review.googlesource.com/27944 inadvertently caused
SHA256 and SHA384 aliases to be rejected in
SSL_CTX_set_strict_cipher_list. While this is the desired end state, in
case the removal needs to be reverted, we should probably defer this to
post-removal cleanup.

Otherwise we might update someone's "ALL:!SHA256" cipher string to
account for the removal, and then revert the removal underneath them.
