Merge #2624

2624: Move runtime environment variables to the end r=nextgens a=ghostwheel42

## What type of PR?

bug-fix

## What does this PR do?

This moves the environment variables used at runtime from the system to the base image.
It's a workaround for a strange build issue observed when building with hardened malloc enabled.
