[PRQ#45847] Deletion Request for dosbox-ex-svn

MarsSeed [1] filed a deletion request for dosbox-ex-svn [2]: Abandoned patched Dosbox from 2018; not a VCS package, uses a pinned revision. Reported failing to build in 2020, and flagged for it since. Better to delete, there are better-maintained alternatives.
