When applying an aspect to a generated file of a Fileset avoid creating the FilesetEntryMap for the aspect's RuleContext.
The current logic in createFilesetEntryMap() uses the rule of the RuleContext.Builder to determine whether to create a filesetEntryMap or not, because of this, applying an aspect to a generated file of a fileset (e.g. 'out' attribute of a Fileset) causes createFilesetEntryMap to create the map even though the associated target is, for instance, a generated file. As a consequence, applying any aspect to a generated file of a fileset causes a NullPointerException.
