KWSys: Remove dependencies on FundamentalType
The hash_fun.hxx header is configured whether FundamentalType is enabled or not and so cannot depend on it. Run the relevant platform tests whether or not FundamentalType is on and configure the result directly into hash_fun. While at it, remove the dependence of SystemInformation on FundamentalType too since it needs only information that we now always compute.
