Move and rename package repositories (part 2)

Catalyst 4 has totally changed the way repositories are handled. It only works when the name of the directory containing the repository matches the configured name of that repository. We already renamed coreos to coreos-overlay accordingly, but we actually want entirely different names and more convenient locations too. The repositories are now known as gentoo-subset and flatcar-overlay, and they live under scripts/repos. Using the same name as upstream Gentoo would have been problematic, and just "flatcar" would have looked awkward in documentation. Signed-off-by: James Le Cuirot <[email protected]>
