Add Containerfile for development

Add a command to create a Debian-based container with the coreboot
toolchains, SDCC and Rust installed in order to minimize the setup time
of a container-based workflow, such as CI.

    make -C containers
    podman run -it --rm \
        -v $PWD:/workspace:Z \
        -v ~/.ccache:/root/.ccache:Z \
        system76/firmware-open:latest \
        ./scripts/build.sh oryp8

A locally built image is 2.86 GiB.
