Add an uninstall wrapper, and move to the stores org

uninstall.sh mirrors install.sh: it names the store and lets the engine do the
work, passing STORE_ID rather than a config URL. install.sh gained what the
Batocera wrapper already had — run from a checkout, it uses the config next to
it rather than the one on the forge.

Both wrappers are POSIX sh now, and neither pipes curl into a shell any more: a
failed download would feed an empty script to sh and look like success, so the
installer is fetched to a file and run from there.

The repository moved from the tools org to stores. The old raw URLs still
redirect.
