e2e_node: check container metrics conditionally

Browse Source 
When PodAndContainerStatsFromCRI FG is enabled, Kubelet tries to get
list of metrics from the CRI runtime using CRI API 'ListMetricDescriptors'.

As this API is not implemented in neither CRI-O nor Containerd versions
used in the test-infra, ResourceMetrics test case fails to gather
certain container metrics.

Excluding container metrics from the expected list of metrics if
PodAndContainerStatsFromCRI is enabled should solve the issue.
