[PRQ#43655] Deletion Request for python-discover

MarsSeed [1] filed a deletion request for python-discover [2]: This dual Python2/Python3 is not needed. It is a backport of unittest discover from Python 2.7+ to Python 2.4. There is no Python 2.4 on AUR. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python-discover/
