    libtracker-miner: Properly honor TRACKER_DIRECTORY_FLAG_CHECK_MTIME
    
    TrackerFileNotifier actually triggered mtime checks more often than
    necessary. All of the sparql queries can be skip, also storing the
    filesystem mtimes (because no sparql mtimes will be queried to
    compare with).
    
    We just need setting up our TrackerFileSystem tree, and adding
    directory monitors, so do this bare minimum.
