TASK: fix Python 3.12 FTBFS in ELN packages

[yselkowitz]

What does the ELN SIG need to do?

The Python 3.12 mass rebuild is about to be merged into rawhide, which will trigger the same in ELN. However, as of the time of merging, there are still packages which FTBFS with Python 3.12. Those that are in the ELN package set need to be fixed quickly so as to not disrupt the forthcoming CentOS Stream 10 import.

pythran is only pulled into ELN by scipy and scipy has been rebuilt without pythran first. a WIP PR is at https://src.fedoraproject.org/rpms/pythran/pull-request/25 but it is not yet fully functional.

pythran fixed

@hroncok the following Python 3.12 issues remain with the ELN package set:
