Fix portability issue in new jsonbsubs code.

On machines where sizeof(Datum) > sizeof(Oid) (that is, any 64-bit
platform), the previous coding would compute a misaligned
workspace->index pointer if nupper is odd.  Architectures where
misaligned access is a hard no-no would then fail.  This appears
to explain why thorntail is unhappy but other buildfarm members
are not.
