[PRQ#62039] Deletion Request for libbatch

MarsSeed [1] filed a deletion request for libbatch [2]: This library is no longer used by any salome packages on AUR (nor by any other builds). Source has been deleted by upstream so now the URL leads to 404 not found. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/libbatch/
