[PATCH] scripts: add container.sh as simple podman wrapper

We have a Containerfile in tree now that is used for CI, but it's not
completely self evident, how to use it locally. Add a simple script
that mounts the current working directory into the container and calls
its arguments inside.

Example building MAKEALL (Some configs will expectedly fail due to size
or firmware constraints):

  ./scripts/container.sh ./MAKEALL

Example starting a shell:

  ./scripts/container.sh /bin/bash
