fix(netbird-proxy-services): numeric runAsUser so runAsNonRoot can be verified

First rollout of #814 sat in CreateContainerConfigError: "container has
runAsNonRoot and image has non-numeric user (controller), cannot verify
user is non-root". The kubelet cannot resolve a named user; nobody/nogroup
in the pod spec is enough, the script needs no home and no writable path.
