[tracker] tracker-preferences: Use the new command line tool

    tracker-preferences: Use the new command line tool
    
    We resort to the tracker CLI for restart/reindex, the calls have
    changed to use Posix.system() as there's some operations that are
    now mutually exclusive in the CLI tool (eg. reset and start daemons)
    and still need to be performed in a single step here.
