health-checker flag deprecation runs into error

Hi, I just tested the new v1.34.0 release and it seems the `health-checker` binary does not work anymore as the flag 'systemd-service' [gets marked deprecated](https://github.com/kubernetes/node-problem-detector/blob/545516f4255d3e9401bfd14289c79b3783eda161/cmd/healthchecker/options/options.go#L56) before it is added to the flag set: ```bash $> docker run -it --entrypoint=/bin/bash registry.k8s.io/node-problem-detector/node-problem-detector:v1.34.0 root@cf12d547cbed:/# /home/kubernetes/bin/health-checker failed to mark deprecated flag 'systemd-service': flag "systemd-service" does not exist ```
