The fun_run library is small but it can stand on its own. I ported it to a crate as an exercise in code cleanup and to remove unnecessary dependencies.

In the migration of the Ruby buildpack to use this crate I noticed a regression:

I isolated it to the `fun_run` PR heroku/buildpacks-ruby#232 and after some debugging found it was due to accidentally copying `child.stdout` for `child_stderr`. I added a test that verifies that stderr is redirected correctly.

Since the feature branch no longer exists.

This will fix Dependabot erroring out with:

```
Errored with the message "Dependabot couldn't fetch the branch/reference for commons"
```

This also required adding `fun_run` as an explicit dependency, due to:
heroku/buildpacks-ruby#232
