The use of unionfs-fuse (57a0f14064)
slows down the KDE 5 test enough that it hits Hydra timeouts. (E.g. on
my laptop it went from ~5 min to ~30 min.) So disable it for the KDE
test.

(cherry picked from commit 3fcbcf2556)
Found out during testing of the Tesseract upgrade the kde5 and sddm
tests don't actually use OCR, so let's disable support for it.
