test-hash: Remove the check_word_hash() for hash_bytes128_cb.

The original test fails on big-endian system due to the hash function
performing not as well when input is uint32_t.  In reality, users should
only use hash_bytes128() to hash words larger than 128 bits (e.g. struct
flow).  Besides, we do check the 1-bit set case for 16 128-bit words in
following test case.  Therefore, the cleanest way to fix the failure
in big-endian system seems to be just removing the check_word_hash()
test for hash_bytes128_cb.
