Fix use of "-w" flag to iptables-restore
iptables accepts "-w5" but iptables-restore requires "-w 5", so kube-proxy is currently broken for people with an iptables-restore new enough that kube-proxy tries to use the new flags.
Fixes#58956
**Release note**:
```release-note
Fixed kube-proxy to work correctly with iptables 1.6.2 and later.
