Subject: [PATCH] python3Packages.pyliblo3: add patch to fix cython compilation
 failure

Fixes #437077
Updating cython from 3.0.12 to 3.1.2 broke pyliblo compilations.
This patch has already been upstreamed but no official release has been
made yet.
Once an official release is made the patch can be removed.
