XAllocClassHint: Assume calloc sets pointers in allocated memory to NULL

While the C standard technically allows for the compiler to translate pointer = 0 or pointer = NULL into something other than filling the pointer address with 0 bytes, the rest of the Xlib code already assumes that calloc initializes any pointers in the struct to NULL, and there are no known systems supported by X.Org where this is not true.
