packagefs: Remove PackageDataV1 from PackageData.

Now that we never access V1 packages in here, we don't need this.
This saves *24* bytes off the size of the class, which is
extremely significant as not only every PackageFile instance
has an instance of this class, but every PackageNode does too;
so the savings from this change is probably in the MB.
