ci: run privileged unit tests only once

[tklauser]

Currently, the privileged unit tests are run twice. Once as a separate
step in the conformance-runtime GH actions workflow [1] and once as part
of the runtime Ginkgo test suite [2]. Keep the former and remove the
latter to only run the tests once and reduce test time.
