provide docker registry override in remaining scripts

As done with fe2768c73, provide a mechanism to override the docker
registry used for our remaining docker scripts.

docker.io continues to tighten control[1] on access to its registry.
Provide a mechanism within this script to utilize a different registry
for the base ubuntu image.

Tested:
- Confirmed script defaults still works as expected
- Confirmed the following also works now:
  export DOCKER_REG=public.ecr.aws/ubuntu
- Confirmed where applicable that this also works(fedora):
  export DOCKER_REG=public.ecr.aws/docker/library
