A benchmark for module loading creates a temporary directory in the benchmark directory. Re-use the test common module to put the tmp directory in test instead. This was causing intermittent test failures because run.js (invoked by benchmark tests, mulitple of which could be running at once) throws if a subdirectory of benchmark disappears at just the wrong time. There are other possible solutions than repurposing the `test/common` module but two arguments for doing it this way are: * There is already another benchmark file that does this (`http_server_for_chunky_client.js`) so the dependency already exists in the benchmarks. * This also eliminates a re-implementation of rimraf in the benchmark code.
