[Build] Optimize the version control for Debian packages (#14557) (#14610)

Why I did it
Optimize the version control for Debian packages.
Fix sonic-slave-buster/sources.list.amd64 not found display issue, need to generate the file before running the shell command to evaluate the sonic image tag.
When using the snapshot mirror, it is not necessary to update the version file based on the base image. It will reduce the version dependency issue, when an image is not run when freezing the version.

How I did it
Not to update the version file when snapshot mirror enabled.
