focal and bionic do not have the required version of python3-magic for the new approach to binary file detection. Accordingly we will patch them with a patch like this,

Description: Remove python3-magic related warning
Do not bother spewing a warning about python3-magic version since
that breaks autopkg tests due to the stderr spew. There's nothing
that we can do anyway about it, since focal would not have the
python3-magic version that sos needs for the new approach.

This is to avoid autopkgtest failures due to the stderr spew of that warning. See https://bugs.launchpad.net/ubuntu/+source/sosreport/+bug/2022915/comments/37
