debugobsolete: also issue the "new obsmarkers" messsage

We are going to improve the way this message is issued in the core codebase.
This will make it appears for `hg debugobsolete` too. Since this seems like a
good idea, we make the output change in a previous changesets to clarify the
next changeset.
