This reverts commit 04fb17cb3f.
- Am seeing a bug where only one worker continues processing
on python3.8.
- Ubuntu and freedesktop-sdk are still on 3.7.
- Not using any features of 3.8 yet.
- Also removes color from mypy.
- This lets the build be tested on a new commit that doesn't
yet exist on github.
- A temporary patched version of the manifest is made with
eris's url patched to the local repo. ($PWD)
- build-flatpak.py needs to be run in the eris root directory.
