"horizon.so" isn't multi-arch safe, so please ensure it gets a suitable
filename on installation.

All CPython modules I can find on my system use one of these forms:
/usr/lib/python3/dist-packages/package.cpython-38-x86_64-linux-gnu.so
/usr/lib/python3/dist-packages/package/module.cpython-38-x86_64-linux-gnu.so
/usr/lib/python3.8/dist-packages/package/module.cpython-38-x86_64-linux-gnu.so

I assume this would normally be done by distutils, or is it handled by
dh_python3 automatically?
