sha256.h: correct definition on SHA224_DIGEST_SIZE

* lib/sha256.h (SHA224_DIGEST_SIZE): Define to 28, not 24.
Reported by Paulie Pena IV <paulie4@gmail.com>.
Define as 224 / 8, rather than as a literal.
(SHA256_DIGEST_SIZE): Define as 256/8 rather than equivalent literal.
* lib/sha512.h (SHA384_DIGEST_SIZE): Likewise, define as equiv: 384/8.
(SHA512_DIGEST_SIZE): Likewise, define as equivalent quotient: 512/8.
