Thomas Huth 645198d58b tests/avocado: Allow newer versions of tesseract in the nextcube test
Current Linux distros ship version 5 of the tesseract OCR software,
so the nextcube screen test is ignored there. Let's make the check
more flexible to allow newer versions, too, and remove the old v3
test since most Linux distros don't ship this version anymore.
