Back when adding support for `pls` as a `sudo` replacement, `build-image-qemu` dynamically set the `SUDO` variable depending on what system it was running on and used the contents of that variable to call the correct elevation utility. During recent changes to the elevation error message, that usage of the variable was replicated across all of our scripts, but without also replicating the logic to set that variable in the first place. Add back the variable setting logic to all the other scripts to keep them from running into unset variables.
