[BUG] WARNING: Failed to get firewall packets in new iptables version

[yuxisun1217]

Describe the bug: A clear and concise description of what the bug is.

After provisioning VM on Azure, see WARNING log in waagent.log:

WARNING ExtHandler ExtHandler Failed to get firewall packets: 'iptables -w -t security -L OUTPUT --zero OUTPUT -nxv' failed: 2 (iptables v1.8.11 (nf_tables): Illegal option `--numeric' with this command
Try `iptables -h' or 'iptables --help' for more information.)

If removing '-n' and '-x', only run "iptables -w -t security -L OUTPUT --zero OUTPUT -v", this command works well:

# iptables -w -t security -L OUTPUT --zero OUTPUT -v
