Unfortunately, prior to this change, `init` might not be called at all. This would be the case for the following pseudo-example:

  int main(void) {
    void *p = memalign(3, 3);
    return 0;
  }

We would go directly to `ScudoAllocator::FailureHandler::OnBadRequest` without going through `initThread` -> `initScudo` -> `initFlags`.
