QCryptographicHash: don't include openssl/sha.h

Browse Source 
... it conflicts with rfc6234/sha.h's SHA{1,224,256,384,512} symbols.

We can't drop the rfc6234/sha.h header, as openssl/sha.h doesn't give
us the algorithm's block sizes, necessary for HMAC
(QMessageAuthenticationCode).

But we can drop openssl/sha.h. The only reason we included the header
was to get access to SHA<N>_DIGEST_LENGTH, but this is a well-known
value and easily obtained from rfc6234/sha.h as SHA<N>HashSize, so use
that.

Even reduces #ifdef'ery.
