In commit 7517aef4d (support/docker: limit the number of layers),
we reduced the number of layers by coalescing multiple RUN commands
into less commands.
In doing so, we especially coalesced "apt-get update" with "apt-get
install".
However, the distribution we used is a pinned version of stretch, so
we know that running apt-get update will always yield the same apt
database.
If we split the two apt-get commands, then we can re-use any local
intermediate image when we need to update the list of packages to
install; this helps quite a bit when testing the docker files over
and over again, with just slight variants in the packages list.

Use the latest version of the tool because it is actively maintained.
But use a fixed version of the tool and its dependencies to get stable
results. It can be manually bumped from time to time.
Before installing any Python packages, ensure pip, setuptools, and wheel
are up to date as recommended in the docs [1].

Some packages build C++ 32bits host-tools and need the g++-multilib to
be installed on the build machine. As example, qt5webengine builds a C++
host-tool when target is 32bits.
Add the check for g++-multilib to the dependencies script; and update
the Dockerfile to install g++-multilib package.

Currently, we refer to the latest version of the image, which means we
can't guarantee any reproducibility. Also, it measn we can't have a
separate images for the maintenance branches (especially the LTS) and
master.
Update the comment in the Dockerfile to create and push tagged images.

Since we're now using a specific base image tag, we need to also use a
specific, stable repository to get additional packages from for this
image.
As such, use the Debian snapshot that matches the base image.

Currently, we are using debian:stable, which is subject to change with
time, as new stable versions of Debian are released/updated.
Use the latest tagged stable release, stretch-20171210 as of today, as
the base distribution to use.
This will ease reproducible builds in the future.

This image is not built very often, and when it is, it is important to
see what's going on, so don't be silent when installing packages from
the distro, and since that can take a bit of time it thus serves as
progress report...

The official documentation [0] suggests limiting the number of layers
generated from a dockerfile. A layer is created for each RUN (and COPY
and ADD) command. But we are only ever interested in the final image,
so the intermediate layers are useless to us.
Limit the number of RUN commands to limit the number of generated
layers.

Currently, our jobs on the gitlab-ci infra are running as root, which is
problematic for two reasons:
- this is not the usual way Buildroot is built;
- it may miss issues where running as non-root is problematic.
So, complement our Dockerfile with directives to add a new user and run
everything as that user, as demonstrated by this build job:
https://gitlab.com/ymorin/buildroot-ci/-/jobs/46929562
Additional, enforce an UTF-8 locale while running.

For Gitlab-CI, we want to avoid re-generating the minimal install to
be able to run tests all the time. So let's create a docker image that
we can post on Docker Hub and then pull.
For the time being, this is just what we need for running our CI. Later
we can produce something that is also useful for users.
