Use long form of "scc" resource type in logging facts

"oc get scc" fails in OpenShift Origin 3.7.1:

  $ oc get scc
  the server doesn't have a resource type "scc"

According to [1] this was lost in a rebase and we were able to identify
it in OpenShift Origin commit 75bcc760f2, file
"vendor/k8s.io/kubernetes/pkg/kubectl/kubectl.go". A workaround is to
use its long form.
