Specify windows attributes in attribute files

This moves windows attributes back to the attribute file.
sous-chefs#95 moved these to the recipe,
however that prevents setting these attributes in a wrapper cookbook's
attribute file.

This ensures that only attributes which depend on jdk_version are set
in the recipe.  All other attributes are set in the attribute file like
normal.
