Why I did it
Enable the reproducible build for PR build for master branch
Fix the reproducible build variable display error in the slave container.
The below config is none, although the config is set and takes effect.
"SONIC_VERSION_CONTROL_COMPONENTS": "none"
How I did it
Passing the variable through the slave container command line.
The variable has been passed to the slave container and the other docker container by a config file, it is only used to display the value during the build.
How to verify it

"SONIC_VERSION_CONTROL_COMPONENTS": "deb,py2,py3,web,git,docker"
