livepatch test configures the system and debug environment to run tests. Some of these actions fail without root access and test dumps several permission denied messages before it exits. Fix test-state.sh to call setup_config instead of set_dynamic_debug as suggested by Petr Mladek <pmladek@suse.com> Fix it to check root uid and exit with skip code instead.
