AppImage: fix PYTHONPATH for system packages
This MR fixes the PYTHONPATH
variable according to the Python docs. We were messing up the lookup path for the subprocess
module, this broke translation retrieval for AppImages.
Requesting review from @dkazakov because I'd like him to check with his Docker environment; I checked with my LXC container and with my Manjaro environment.
Test Plan
Build Krita using an isolated environment similar to ci-tooling's Docker images.
