devtool: fix poor handling of upgraded BBCLASSEXTENDed recipes
Fix two aspects of handling BBCLASSEXTENDed targets (e.g.
openssl-native) that have been run through "devtool upgrade":
* Fix recipe name not showing up in "devtool status"
* Fix "devtool reset" not deleting empty directories under the recipe
directory within the workspace, which may lead to problems if you
subsequently run "devtool upgrade" on the same target again
