[PATCH v2 14/14] t4009: make hash size independent

["brian m. carlson" <sandals@xxxxxxxxxxxxxxxxxxxx>]

Instead of hard-coding object IDs, compute them and use those in the
comparison.  Note that the comparison code ignores the actual object
IDs, but does check that they're the right size, so computing them is
the easiest way to ensure that they are.
