Aren't those constants now defined in `ktap_helpers.sh` as well, i.e.,
could those be removed here?

Definitely, I forgot to remove them. Thanks for the heads up!

I also noticed there's a ktap_finished function now available that
prints the results summary and handles the return code, so the test
script can be simplified further.

v3 includes these changes: https://lore.kernel.org/linux-kselftest/20240222162913.498197-1-laura.nao@collabora.com/T/#u
