.github/labeler: add exclusive cilium-cli label

As we have merged cilium-cli into cilium repository, we don't need to
generate release note labels for PRs that are specific for cilium-cli
when preparing the release notes for cilium. The same logic applies for
hubble-cli.

When generating the release notes for cilium we will exclude all PRs
that have the cilium-cli-exclusive and hubble-cli-exclusive labels.
