The latest upstream commit drops legacy Python 2 support code.

Following this update we can drop the RDEP on py-future. However testing 
this change revealed that fifengine was missing an RDEP on py-future. The 
fix for fifengine is already in the tree, but I updated the fifengine RDEP 
here to 0.4.2p4 to make sure py-future continues to stay around at 
runtime.

The TDEP on py-nose was removed upstream in commit 3a808be which switched 
to pytest. (But tests are still broken as they do not support pytest 4+ 
yet.)

Also switch to using MODPY_SETUPTOOLS=Yes which seems to work (possibly 
after upstream commit 50397fa.

ok?
