These are typically auto-extracted with modify/upgrade from recipes
and can be easily recreated. On the rare occasions where they need
to be reused, they are still available under workspace/attic (which
is already used for old recipes and appends), so nothing gets lost.
This avoids the annoyance of devtool refusing to proceed because
there is a previous source tree in workspace/sources.
For independent source trees behave as before: do nothing.
Adjust the test that previously deleted those trees by hand.
