[PRQ#50219] Deletion Request for xz-static

MarsSeed [1] filed a deletion request for xz-static [2]: Unneeded static variant of core/xz. Not updated with upstream releases since 2022-10. Previously was used as makedepend by AUR/libvirt-sandbox; this is no longer the case. Safe to delete. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/xz-static/
