[PATCH 1/6] pyenv: also install requirements for python2

[Daniel Axtens]

The first time you do a migration with python3, you get a whole
lot of seemingly null changes. This is a bit annoying so I use
py2 to generate the changes. To do that, first fix the pyenv
transition so requirements are still installed for python2.
