make hack/markdown-preprocess parallel-safe

One of the tmpfiles was not uniquely named, resulting in conflicts with parallel 'make docs'. Fix that. A better solution would be to run only one instance of the preprocess script, but the Makefile incantation for that is beyond me. This approach is CPU-wasteful but good enough.
