[PATCH 6/6] test-hashmap: use "unsigned int" for hash storage

The hashmap API always use an unsigned value for storing and comparing hashes. Whereas this test code uses "int". This works out in practice since one can typically round-trip between "int" and "unsigned int". But since this is essentially reference code for the hashmap API, we should model using the correct types.
