Add NAT kernel config required by docker

I received docker errors below on the new BSP:

INFO[2024-03-04T21:00:14.262170118Z] Loading containers: start.

iptables v1.8.4 (legacy): can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.`, error: exit status 3

So I added NAT kernel configs

LGTM, I like this addition!

@mistyron I enabled more configs since the time you approved it. These extra configs were later discovered when iotedge was not working properly and I discovered this script:
