docker build image --> addgroup: The GID `0' is already in use

[vpetrucci]

When using Docker script "./docker/benchbase/build-full-image.sh", the "RUN addgroup ..." command fails with the following msg "addgroup: The GID `0' is already in use."
A quick and dirty fix was to change these ARG variables as follows:
ARG U_ID=1000
ARG G_ID=1000
System used was Alma Linux 9 (podman-docker: 4.0.2-7)

@vpetrucci Can you send a PR?

I see the problem.
The command was designed to run as non-root user.
I'm happy to help review a PR if you have one, else I'll try and take a stab at it tomorrow.

Here's a draft PR that addresses part of the problem: #194
Update: I extended the PR to handle overlapping UID/GID within the container and published it.

Sorry for being slow to this. Thanks @bpkroth, that explains the issue (me running as root) and your patch makes sense to me. Thanks again for the prompt response and fix.
