tests: k8s: Remove tests running on GitHub provided runner

We have 2 tests running on GitHub provided runners:
* devmapper
* CRI-O

- devmapper situation

For devmapper, we're currently testing devmapper with s390x as part of
one of its jobs.

More than that, this test has been failing here due to a lack of space
in the machine for quite some time, and no-action was taken to bring it
back either via GARM or some other way.

With that said, let's rely on the s390x CI to test devmapper and avoid
one extra failure on our CI by removing this one.

- cri-o situation

CRI-O is being tested with a fixed version of kubernetes that's already
reached its EOL, and a CRI-O version that matches that k8s version.

There has been attempts to raise issues, and also to provide a PR that
does at least part of the work ... leaving the debugging part for the
maintainers of the CI. However, there was no action on those from the
maintainers.
