Use zip_safe=False in setup() call

As noted in:
  https://github.com/travis-ci/travis-ci/issues/9119
Apparently Travis-CI is trying to build numpy for the latest CPython
3.7-dev snapshot, and getting a bizarre error in setuptools:

Traceback (most recent call last):

I don't know why that code is crashing, but it looks like the code
that's crashing is scanning numpy trying to figure out if it's
"zip_safe". Numpy is definitely not zip_safe, so we might as well tell
setuptools that and it can stop trying to guess.
