tools: Add a script to switch between coreutils and rust-coreutils

These being essential packages, a script is needed to backup binaries used to do the upgrade.

https://phabricator.apertis.org/T8572

changed the description

This change looks OK to me, however I think the script is specific to rust-coreutils but would make this script a bit more general to allow switching from GPL-3 free packages to standard ones, including cpio, grep, gzip, tar, sed, findutils

Also it is important to note that there is already a script for similar purpose

https://gitlab.apertis.org/infrastructure/apertis-image-recipes/-/blob/apertis/v2023dev2/overlays/apertis-dev/usr/sbin/apertis-dev

Probably I was confused by the name (apertis-dev) when I mentioned the script, which is not is repo but in the apertis-image-recipes.

So my suggestion would be to close this MR and make sure the apertis-dev provides all the replacement needed for switch to a standard system. Do you agree?

Do those other packages have issues when being removed as well ? This was just to cover the case of coreutils that needs rm to be replaced.

Do you think the script should be more generic and switch all packages between their C and Rust versions ?
