[bug #61009] xargs need option to immediately stop on command fail

Follow-up Comment #4, bug #61009 (project findutils):

The proposed 

find . -type f | xargs -IX -n1 sh -c "cp -f X $IMGDIR_DST/X || exit 255" ||
exit 1


can be implemented more efficiently without using the hypothetical -F flag:

find . -type f -exec cp -t "${IMGDIR_DST}" {} + -o -quit

This approach is also less "complex and error prone" than the approach using
xargs and lots of flags.
