Remove setting of universal wheels (#3367)

dopplershift · max-sixty · commit dd2b803a28cd · 2019-10-02T17:43:44.000-04:00
Universal wheels indicate that one wheel supports Python 2 and 3. This
is no longer the case for xarray. This causes builds to generate files
with names like xarray-0.13.0-py2.py3-none-any.whl, which can cause
pip to incorrectly install the wheel when installing from a list of
wheel files.
