Change container builder from Docker to Buildah/Podman

[peterlobster]

Details

There has been a recent trend moving away from Docker's original tooling, in favor of tooling with better OCI support. My suggestion is to update the tooling for building this container to something that could be either compatible with both Docker and OCI tooling (like Podman) or to add an option to use something like Buildah to build an OCI compatible container image.

Currently, the container is being built with Docker and fails to build with Podman (when using Podman-Docker aliasing).

Could you please share the errors you encounter when trying to build with Podman?

podman build --no-cache -t phusion/debian-baseimage-docker:focal-1.0.0-pre --build-arg BASE_IMAGE=registry.hub.docker.com/library/debian:stable --build-arg QEMU_ARCH=amd64 --platform 
Error: flag needs an argument: --platform

You seem to be missing an argument, and thus it fails but unfortunately it's been a while since I have tried to build it via make, and should probably update it. It however should currently work when you pass in --platform amd64 for example.
