    tools: one more optimization of gimp-check-mirrors script.
    
    Actually we don't need to wait for the original file checksums to be
    completed first before starting to download and compute the checksums of
    the mirror files. Let's just pass the concurrent.futures.Future object
    to the mirror check threads and let these wait for us if the original
    checksum was not finished yet.
