patches: Remove native code from setup.py

This patch to setup.py prevents pip from trying to compile the C/C++
shapely sources when building the Unikraft Python rootfs, since we never
make use of these compiled files.
This prevents build failures when the host system lacks dev files for
shapely dependencies.

+Subject: [PATCH 2/2] setup.py: Remove natively-compiled modules
+
+This change removes any reference to C/C++ modules as well as any
+cythonized sources from setup.py, since Unikraft handles building these
+modules. Thus, only python files will be installed by pip.
