devtool: handle virtual providers

For modify / extract / upgrade, if the specified "recipe" is not
actually a recipe but a virtual target such as virtual/kernel, map it
correctly to the actual recipe and make sure we use that name within the
workspace. Thanks to Chris Larson for reminding me this was still broken
and for a hint on how to fix it.
