tools: add "--quiet" option to only log libinput messages
Supresses any printf statements from the tool itself, i.e. it skips printing any of the events. Makes it easier to debug the internal state since it's not intermixed with a whole lot of messages about the events that are generated. Best combined with --verbose (yes, hilarious, isn't it...)
