pip install monetdblite on linux installs Mach-O binary

It seems as if the wheel delivers a Mac binary for libmonetdb5.so.

Broken:

docker run -it --rm python:3.6 bash -c 'pip install numpy && pip install monetdblite && file /usr/local/lib/python3.6/site-packages/monetdblite/libmonetdb5.so && python -c "import monetdblite"'

Workaround by forcing non-wheel installation:

docker run -it --rm python:3.6 bash -c 'pip install numpy && pip install --no-binary monetdblite monetdblite && file /usr/local/lib/python3.6/site-packages/monetdblite/libmonetdb5.so && python -c "import monetdblite"'

Note the use of --no-binary monetdblite to make it work.
