test: hashmap - cripple the hash function by truncating the input rather than the output
The reason for the crippled hash function is to reduce the distribution of the hash function, do this by truncating the domain rather than the range. This does introduce a change in behavoir as the range is no longer contiguous, which greatly reduces collisions. This is needed as a follow-up patch will no longer allow individual hash functions to alter the output directly.
