packaging: reference proper output directory

9438e9b7321a changed the name of the PyOxidizer target, which changed
the name of the output directory. The code changed by this patch
wasn't properly updated by that changeset. This resulted in a run-time
failure due to trying to read from a non-existent directory.

This change should fix the building of Python 3 Inno installers.
