You can achieve that with:
diff --git a/debian/rules b/debian/rules
index 8c83e2741..e97efcc3b 100755

However, the problem is that the current autopkgtest has "#!
/usr/bin/python3", so you'd have to fix that too; I'm not sure exactly
how that would look. Presumably users expect it to work with the
default Python as well.
I tend to think that the dependencies suggested by Adrian would be a
better fit here. You can achieve that with something like this
(slightly hacky, but it's the simplest approach I can think of):
