The selinux_set_labels function should run as late as possible. To guarantee that, we append it to IMAGE_PREPROCESS_COMMAND in RecipePreFinalise event handler, this ensures it is the last function in IMAGE_PREPROCESS_COMMAND. After refactoring, system using systemd can also label selinux contexts during build.
