Kubernetes: Fix kube-proxy nftables Crash with Newer nftables

Problem

kube-proxy in nftables mode crashed on systems running nft 1.1.3. The nftables implementation in kube-proxy wasn't compatible with the newer nftables version's behavior.

Solution

Updated kube-proxy's nftables implementation to work correctly with nft 1.1.3. Adjusted command parsing and rule handling to accommodate the version-specific behavior changes.

Result

kube-proxy works correctly in nftables mode on modern Linux systems running nft 1.1.3+.
