[tracker/wip/carlosg/tracker-3.0-api-breaks: 26/63] examples: Drop class-signal example code

    examples: Drop class-signal example code
    
    This example essentially demonstrates GraphUpdated DBus signals, which
    are deemed an internal API detail. An example using TrackerNotifier might
    be useful, but this code isn't much salvageable to be repurposed.
