Fix issue with using locally defined attrs in a shared lib
The attribute name resource IDs were never fixed up with
the runtime package ID so we weren't finding attributes
whenever the runtime package ID was different than the build
time one, which happened to be when a shared lib referenced itself
(0x00 vs 0x02).
