    Fix compiler warnings with openssl-scrypt/libscrypt test on clang
    
    Clang didn't like that we were passing uint64_t values to an API
    that wanted uint32_t.  GCC has either not cared, or has figured out
    that the values in question were safe to cast to uint32_t.
    
    Fixes bug22916; bugfix on 0.2.7.2-alpha.
