Only the KDF and PRF algorithms used the macros for their names, all other algorithms used a string name directly. This brings the KDFs and PRFs into line with the rest. Reviewed-by: Matt Caswell <matt@openssl.org> (Merged from https://github.com/openssl/openssl/pull/10293)

* SUBNAME may be present where we are combining multiple
|
|
* algorithms together, e.g. MD5-SHA1.
|
|
*
|
|
* SIZE is only present if multiple versions of an algorithm exist
|

* with different sizes (e.g. AES-128-CBC, AES-256-CBC)
|
|
*
|
|
* MODE is only present where applicable.
