    tools: display the total check count also when showing error count.
    
    It gives a better sense of the share of mirrors not synced yet. It's
    indeed not the same thing when you have 10 errors out of 29 download
    tests or out of 87 (when looking all downloads, i.e. source tarballs,
    Windows installer and macOS package like I did just now for checking the
    mirror sync for GIMP 2.10.30).
