[PRQ#43254] Deletion Request for libmdcpp-git

MarsSeed [1] filed a deletion request for libmdcpp-git [2]: Broken library pkg from 2016 for discontinued KDE note-taking app marketo-git. Submitted deletion for that as well, because both are discontinued since 2017 and both AUR packages are broken. No comments since 2016.
