Update hacking for Python3

The repo is Python using both Python 2 and 3 now, so update hacking to
version 2.0 which supports Python 2 and 3. Note that latest hacking
release 3.0 only supports version 3.

Fix problems found.

Remove hacking and friends from lower-constraints, they are not needed
for installation.
