    tracker-extract-pdf: fix uninitialized value
    
    'bytes_remaining' needs to be initialized to the 'bytes_expected' value, so that
    the proper amount of remaining bytes is kept during the outer while() loop. In
    the first iteration, this will be -1, which will then be updated to afterwards
    to the same 'bytes_expected' value read from the stream.
