[PRQ#59380] Deletion Request for mate-panel-gtk2

MarsSeed [1] filed a deletion request for mate-panel-gtk2 [2]: Broken, EOL version from 2017 of repo's newer mate-panel. Has been failing to build for some time, and now it is also missing dependencies that have already been deleted for the same reason.
