In init_system_properties_values() NEW_C_HEAP_ARRAY is defined to malloc.
After calls to this macro, the result was checked for NULL.

Actually, NEW_C_HEAP_ARRAY exit the vm if it can not allocate memory.

Remove the misleading malloc macro and remove unnecessary checks for null
in os_linux.cpp and os_aix.cpp.
Or, you can change to NEW_C_HEAP_ARRAY_RETURN_NULL if you do want to handle the allocation failure.
