Add expected output for tests

Expected output generated by OpenSSL (see below) apart from the case
where both password and salt are either NULL or zero length, as OpenSSL
does not support this. For these test cases we have had to use our own
output as that which is expected. Code to generate test cases is as
follows:

 #include <openssl/pkcs12.h>
 #include <openssl/evp.h>
 #include <string.h>

int Keygen_Uni( const char * test_name, unsigned char *pass, int
    passlen, unsigned char *salt,
                    int saltlen, int id, int iter, int n,
                                    unsigned char *out, const EVP_MD
                                    *md_type )
{
   size_t index;

   printf( "%s\n", test_name );

   int ret = PKCS12_key_gen_uni( pass, passlen, salt, saltlen, id, iter,
                                        n, out, md_type );

   if( ret != 1 )
   {
         printf( "Key generation returned %d\n", ret );
      }
   else
   {
         for( index = 0; index < n; ++index )
         {
                  printf( "%02x", out[index] );
               }

         printf( "\n" );
      }

   printf( "\n" );

}

int main(void)
{
   unsigned char out_buf[48];
   unsigned char pass[64];
   int pass_len;
   unsigned char salt[64];
   int salt_len;

   /* If ID=1, then the pseudorandom bits being produced are to be used
