Add Containerfile for development

Add a command to create a Debian-based container with the SDCC and Rust
toolchains 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 \
        system76/ec:latest \
        make BOARD=system76/oryp8
