chore(3p/emacs): Remove obsolete third-party packages r/2533
We don't need these in the depot anymore as the Emacs overlay now provides newer versions of them, or because they are not used anymore. Change-Id: I393e1580b66450d0bb128213bc79668172dadacc Reviewed-on: https://cl.tvl.fyi/c/depot/+/3005 Tested-by: BuildkiteCI Reviewed-by: grfn <grfn@gws.fyi>
