bootstd: Add a return code to bootflow menu
Return an error when the user does not select an OS, so we know whether to boot or not. Move calling of bootflow_menu_run() into a separate function so we can call it from other places. Expand the test to cover these cases. Add some documentation also, while we are here. Signed-off-by: Simon Glass <sjg@chromium.org>
