    tracker-miner-fs: Process only one item at a time
    
    Despite us spawning a number of tasks (10 currently) to process
    files in parallel, disk access is a bottleneck to them. Reduce
    this to 1, it doesn't seem to impact performance that much, and
    it does help in not processing files together that may not go
    in the same SPARQL update batch.
    
    This is irrelevant now, since the operation would be blocked by
    the parent being still processed, but we want to lighten that
    block in future commits.
