source/cpu: drop deprecated cpu-rdt labels

Drop RDT labels that were deprecated in NFD v0.13. The RDT features
remain available for NodeFeatureRules to serve custom labeling.

-> **NOTE:** the `cpu-rdt.<rdt-flag>` labels are deprecated and will be removed
-> in a future release. They will remain to be available as features
-> for [NodeFeatureRule](custom-resources.md#nodefeaturerule) to consume.
-> See [customization guide](customization-guide.md#nodefeaturerule-custom-resource)
-> for details how to use NodeFeatureRule objects to create labels.
