license: Fix and extend recommendations for license packages.

Changed package recommendations so that the license package of a
recipe is recommended for all packages of a recipe instead of for one
package given by the recipe name.

Pre-patch behaviour results in a missing recommendation when a recipe
does not have a package with the same name.
