Download busybox from the Hub instead of GitHub

This downloads a specific image ID of `busybox:latest` from the Hub directly (within the `Dockerfile`, ready for `docker load`) instead of grabbing the source from GitHub and doing a `docker build` at daemon start time.  This ensures the test suite runs more consistently.
