Windows doesn't have headers unistd.h, sys/wait.h, so remove them for _WIN64. Also, Windows doesn't have rand_r so define it. Fixes builds for HIP tests: d2dMemCpyWithPinnedHostMemory, hipMemset3DFunctional, hipModuleLoadMultProcessOnMultGPU, hipModuleLoadUnloadStress, hipModuleNegative, hipStreamACb_ThrdBehaviour, hipMemcpyNegativeMThrdMSize, hipStreamACb_MStrm_Mgpu, StreamAddCallback, hipStreamACb_StrmSyncTiming, hipStreamACb_MultiCalls, hipMallocConcurrency, hipMemset3DRegressMultiThread, and hipSetGetDevice.
