[PRQ#48587] Deletion Request for lib32-qjson

MarsSeed [1] filed a deletion request for lib32-qjson [2]: Abandoned Qt4 package from 2017. As lib32-libdbusmenu-qt is for optional Qt4 based desktop integration, which is no longer needed, I submitted it for deletion (PRQ#48584). It is safe to drop this after that one.
