cache/template.__getitem__: filter INHERITED

Never return INHERITED, since portdbapi.aux_get() will generate it
automatically from _eclasses_, and we want to omit it in comparisons
between cache entries like those that egencache uses to avoid redundant
writes (see commit 0e120da008c9d0d41c9372c81145c6e153028a6d).
