[PRQ#59317] Deletion Request for python2-pyliblzma

MarsSeed [1] filed a deletion request for python2-pyliblzma [2]: EOL Python2 bindings to liblzma (xz). Its only reverse dependency was yum, which is EOL since 2011 and hasn't worked on Arch Linux for at least the past 3 years. (Its AUR package has already been deleted in response to PRQ#58748). Therefore this build no loner has a use case and can safely be deleted from AUR. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-pyliblzma/
