cilium: add k8sServiceHost fallback for clusters missing cluster-info CM

[ajoaugustine]

cluster-info ConfigMap is missing on some EKS clusters, which breaks k8sServiceHostRef lookup, causing CreateContainerConfigError on Cilium pod startup.
Added k8sServiceHost to the values file. When set to the Kubernetes API server hostname, Cilium skips the cluster-info ConfigMap lookup entirely. Clusters that already have cluster-info ConfigMap do not require any changes.
