SRU: backport Python 3.8.5 to 20.04 LTS

[Matthias Klose]

Backport python3.8 3.8.5 to focal

Test rebuild for focal (main) was done together with the compilers, and showing good results. See LP: #1879481.

Regression potential: python-babel needed an adjustment for a test case (no changes to the code itself). Trying to minimize the potential with the test rebuild.

Validation: Test results show no regressions, and the archive test rebuild doesn't show any regressions.

Status changed to 'Confirmed' because the bug affects multiple users.
