[tracker] libtracker-extract: fix dummy_module

    libtracker-extract: fix dummy_module
    
    The ModuleInfo typedef contains 6 items, of which the last is 'optional' (predefined).
    
    TRUE as parameter for TrackerExtractShutdownFunc though is not a good idea: it's used as an
    integer and passed as a pointer to a function call.
    
    As there is no shudown function for the dummy module, just pass an additional NULL in there.
