tinfoil: fix log message doubling when config_only=False

With config_only=False we launch the UI and it sets up a logger, whereas
when config_only=True we don't, with the result that with True we are
seeing log messages from both our logger and the one set up by the UI.
Suppress our loggers with config_only=True to avoid this.

Fixes [YOCTO #11275] (again).
