packaging: Mount $HOME/.docker in the 1st layer container

In order to ensure that the proxy configuration is passed to the 2nd
layer container, let's ensure the $HOME/.docker/config.json file is
exposed inside the 1st layer container.

For some reason which I still don't fully understand exporting
https_proxy / http_proxy / no_proxy was not enough to get those
variables exported to the 2nd layer container.

In this commit we're creating a "$HOME/.docker" directory, and removing
it after the build, in case it doesn't exist yet.  The reason we do this
is to avoid docker not running in case "$HOME/.docker" doesn't exist.

This was not tested with podman, but if there's an issue with podman,
the issue was already there beforehand and should be treated as a
different problem than the one addressed in this commit.

Fixes: #5077
