[PRQ#43168] Deletion Request for lib32-libgcrypt15-git

MarsSeed [1] filed a deletion request for lib32-libgcrypt15-git [2]: Leftover pkg from 2019 for legacy v1.5 line. VCS build not needed for this branch: latest commit is from 2016. Arch repo still carries the last stable lib32-libgcrypt15. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lib32-libgcrypt15-git/
