macos: Do not build packages for Python 3.5

3.5 is no longer supported by Python.org and installation fails due to
  download certificate failures:

  + PIP_CMD='/Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5 -m pip'
  + /Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5 -m
    pip install --upgrade pip
    Could not fetch URL https://pypi.python.org/simple/pip/: There was a
    problem confirming the ssl certificate: [SSL:
    TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version
    (_ssl.c:719) - skipping
    + '[' -z '/Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5 -m pip' ']'
