Why I did it
Add the missing debian source bullseye-updates/buster-updates
The build failure as below, it is caused by the docker image debian:bullseye used the version 2.31-13+deb11u5, but the version only available in bullseye-update.
This change adds support to build dockers using buster as base.
- Define docker-base-buster using docker-base-stretch as starting point
- Define docker-config-engine-buster using docker-config-engine-stretch as starting point.
- sonic-mgmt-framework docker is updated to build using buster as base
