Tests: show debugging hint when USDStageCreationTest fails 

Setting the environment variable `PXR_PATH_DEBUG` non-empty will make the
USD library print the directories it uses to find its JSON files. This can
aid in debugging when this unit test fails. Now the failure message also
tells you about this.

No functional changes.
