Subject: Porting existing code over to Python3 by using 2to3

Upstream has done some usage of 2to3 in real time to convert the source
code into Python3 compatible code.
This requires the existence of 2to3 at build time, but Debian is only
supporting Python3 for some time. This patch does nothing more than the
patching of the source which was done by 2to3 in real time before.

This patch should become obsolete once upstream will completely move to
support Python3 only.

Forwarded: not-needed
