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@xxxxxxxx>
Fix it to check root uid and exit with skip code instead.
