[PRQ#49648] Deletion Request for python-oslo-privsep

MarsSeed [1] filed a deletion request for python-oslo-privsep [2]: Cleanup of unused, unmaintained OpenStack server Python module. Submitter completely MIA since 2022-11. OpenStack maintains hundreds of Python components, with frequent updates. Better drop all related abandoned packages from AUR and let people install them when needed from PyPI.
