Use OpenSSL-specific ifdefs in sha2.h

In order to separate OpenSSL's SHA symbols, this header has been using
USE_SSL, which is equivalent to USE_OPENSSL.  There is now only one SSL
implementation included in the tree, so this works fine, but when
adding a new SSL implementation this would run into failures.
