Test bluechi-agent-user-bus stopped working in GitHub CI as well, it was disabled in Testing Farm earlier.
Now it fails in both environments with the same error.

Couldn't we simply create a user in the container, e.g. via

RUN useradd bluechi

and use that instead of stitching it together on the fly?
As long as we don't add USER bluechi we still run as root by default, but are able to use the user bus for bluechi user, e.g. via

systemctl --user -M bluechi@ status bluechi-agent

The specific test could then be changed to listen on the connection state, then calling this systemctl command and exit.
