.cqfd/docker/check_yaml.sh: update script

The script's output was always 0, even if yamllint found errors in the
syntax.
Now, if no error is detected on a file, OK is printed in green next to
the file's name.
If an error is detected, KO is printed in red next the file name, the
error is printed.
Finally, the total number of errors is printed and the script exits with
1 if errors were detected.
