cgroup: skip unified if we are using v1
There exists a chance for a node to be booted in v1, but have reminents of v2. An example is this CRI-O ci run: https://deck-ci.apps.ci.l2s4.p1.openshiftapps.com/view/gcs/origin-federated-results/pr-logs/pull/cri-o_cri-o/3565/test_pull_request_crio_critest_fedora/11243/
We fail because we are incorrectly writing to the unified path, because we are v1. We should not write to the unified path if we are v1
