Fix: AMI product codes need to be defined

Fix: AMI product codes need to be defined

While trying to upgrade the internal Jenkins to latest global-jjb and
common-packer it's been found that all of our configurations for AWS
systems are missing vital filters.

The Ubuntu product codes were found by doing the following:

aws ec2 describe-images --region us-west-2 \
  --owners aws-marketplace --filters \
  "Name=architecture,Values=arm64" \
  "Name=name,Values=*ubuntu*20.04*" \
  "Name=manifest-location,Values=aws-marketplace/ubuntu/*"

This is per documentation found at
https://ubuntu.com/server/docs/cloud-images/amazon-ec2
