all autopkg tests triggered by python3.9 pass, all autopkg tests

1 test failed:
test_ttk_textonly
this test is already ignored for python3.9, and also will be ignored
with the pending update of 3.8 to 3.8.10, tracked in LP: #1928057.
Suggesting to ignore that one here, the Tcl/Tk bindings are not much in
use, and checked that idle continues to work with the update.

results
- - 20.04 LTS and 20.10: not used in the archive, just check test suite
