[Buildroot] [PATCH 0/5] support/docker: make the image more reproducible

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

Currently, the base test image is not entirely reproducible, because we
install packages from PyPI without specifying all the versions of all
the packages we install from there.

Instead of relying on a third-party to provide packages, just use those
from the distribution, because we are using a pinned version and thus
we will always get the same packages from the distro.

Eventually, we also update to a python3-flavoured flake8, as that
catches even more issues. Those issues are also fixed. Note that, even
if we decide against switching to a python3 flake8, we can still apply
patch 4, to fix the issues that it reported.

The result of using this series can be seen at:
    https://gitlab.com/ymorin/buildroot-ci/pipelines/23095050

If/when this series is applied, I'll regenerate and updalod the new
buildroot/base image, and send a furhter patch to use it from our
gitlab-ci.yml.


Regards,
Yann E. MORIN.
