Run UT as root inside the container
Run UT as root inside the container

The code coverage module requires the /code directory to be
writable, which it won't be if the UID of the user outside the container
doesn't match the UID of the `user` user inside the container.

Running under `user` is only required for pyinstaller, not UTs.
