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

[Jeff King <peff@peff.net>]

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.
