I don't see check-avocado on the custom runners job descriptions
(.gitlab-ci.d/custom-runners/ubuntu-22.04-aarch64.yml). It seems we
don't run avocado there at all.

For the regular jobs, there's the avocado-cfi-aarch64 job which depends
on the build-cfi-aarch64 job that is being skipped at the moment. But
that wouldn't catch this bug because it runs on an x86 host and this
particular test gets skipped.
