For now, building python3-systemd sometimes reports error:

  pyutil.o not found

This is because its setup.py is not written in a way to handle
race condition. Multiple modules are using the same .c file,
resulting in the corresponding .o file generated multiple times.

The latest release of python3-systemd is 235, and the latest codes
have switched away from setup.py. So we'd better not patch setup.py.
Instead, we handle this issue by making its modules compile one by
one. It only has 5 modules, so there should be little impact on
building time.
