rustbuild: fix local_rebuild

If we detect a local rebuild (e.g. bootstrap compiler is the same version as target compiler), we set stage to 1. When trying to build e.g. UnstableBook, we use Mode::ToolBootstrap and stage is 1. Just allow Mode::ToolBootstrap and stagge != 0 if we are in a local_rebuild Signed-off-by: Marc-Antoine Perennou <[email protected]>
