BUG: setup.py: write version.py only after switching to Py3 build dir

pv · pv · commit 0131218566f5 · 2010-11-23T18:05:42.000+01:00
This prevents importing non-2to3'ed numpy in Python 3 build, if
numpy/version.py exists for some reason but .git does not (e.g building
multiple Numpy versions from same source tree).
