tests/e2e: Remove kata-containers test

Remove the kata-containers `CCv0` e2e tests in the operator
as these tests are on a dead branch of a dead repo
We also have had issues with them not being suitable as they
programmatically change the configuration, which isn't likely to work
in GHA, but isn't what we want to test either.

Later we should add an e2e smoke test that ensures that the kata-payload
integrated with things like nydus-snapshotter than the operator
is responsible for setting up and configuring as discussed in
confidential-containers#239

Collapse all the runtime classes to do the same tests for now
and then when we add the smoke test we can make that have the
smarts to handle all the platforms
