Re-implement the test using simpler approach. Enable it only when doing an out-of-source build with a `.git` source. Run it last, serially. Re-use the `git` tool found for version computation. Print the output from `git status` without modification. Rely on `.gitignore` instead of filtering out paths ourselves.
