    scanner: Don't process pkg-config libs twice
    
    Before, we were adding the --libs-only-L from pkg-config files
    during initial scanning, as if --library-path was specified,
    *and* inside the dumper, we used --libs.
    
    Fix this by always doing -L. <introspected libraries> <pkg-config libs>
    
    This should ensure we don't duplicate the search path anyways.
