Revert "Fix wrong path for dhclient.conf on RedHat/CentOS"

Current design expects users to define at least one
nameserver in the nameservers var to backup host OS DNS config
when the K8s cluster DNS service IP is not available and hosts
still have to resolve external or intranet FQDNs.

Fix undefined nameservers to fallback to the default_resolver.
