Bug#893736: glib2.0 FTBFS: ModuleNotFoundError: No module named 'distutils'

[Jeremy Bicha]

Control: found -1 2.54.3-2

I am uploading a fixed glib2.0 soon, but let's let the current version
migrate to Testing to not block several pieces of GNOME 3.28. The bug
is triggered by the recent python3.6 upload.

Thanks,
Jeremy Bicha
