Improve run-test tooling support

A useful thing to do with run-test tests is to run them in parallel to
reproduce low-probability flakes. We have a tool called
parallel_run.py to do this. Unfortunately one had to manually create
the script that parallel_run.py would execute, making it rather
difficult to use. This adds a --create-runner flag to run-test that
will cause it to write a script (called $DEX_LOCATION/runit.sh) that
is compatible with parallel_run.py

Test: % ./test/run-test --host --64 --prebuild 001-HelloWorld
      ...
      Runnable test script written to /tmp/allight/test-180018/runit.sh
      ...
      % ./tools/parallel_run.py /tmp/allight/test-180018/runit.sh -j80
