include xdg-user-dirs xdg-utils packages in the Docker image

[qhaas]

A number of users see the following (seemingly) harmless warning when using the docker image and become concerned or
worse, it becomes a red herring while troubleshooting unrelated issues:

sh: 1: xdg-user-dir: not found

Recommend deploying the xdg-user-dirs xdg-utils packages in the Docker image to prevent this warning from appearing and reduce the number of issues posted here and/or time spent by users who see this as the last console entry and assume it has something to do with whatever issue they are experiencing.

@bernatx could you have a look at this and provide your opinion?

A less invasive approach would be to find a way to suppress said warning, which I have not yet discovered. Adding said additional packages might have unintended consequences beyond a larger image.

Since this continues to be a red herring with the community and is likely an UE nuance, I asked over in UE Answers how to suppress it.

This is still not fixed, is it?
