[Build] Change the default mirror version config file (sonic-net#13786)

Why I did it
Change the mirror config file
Use the files/build/versions/default/versions-mirror only when reproducible build enabled.
The config in files/build/versions is only for reproducible build, while snapshot mirror feature does not have the dependency on the reproducible build.

How I did it
Skip the mirror config in files/build/versions/default/versions-mirror if reproducible build not enabled.

How to verify it

scripts/build_mirror_config.sh
