[PRQ#44771] Deletion Request for lib32-libsigc++

MarsSeed [1] filed a deletion request for lib32-libsigc++ [2]: Unused lib32 callback framework, legacy v2 version. It last consumer was bin32-vmware-server-console, broken since 2018-04 and deleted in 2022. Only I flagged this OOD a year ago but no one noticed. I also don't need this package. Last comment is from 2019. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lib32-libsigc++/
