* Function: test_path_env
*
* Purpose: Test whether the value of HDF5_EXTFILE_PREFIX will overwrite
* the efile_prefix dataset access property.
* This will create an HDF5 file in a subdirectory which will
* refer to ../extern_*a.raw
* The files are then accessed by setting the HDF5_EXTFILE_PREFIX
* environment variable to "${ORIGIN}".
* The efile_prefix dataset access property is set to "someprefix",
* which will cause an error if the value is not overwritten by
* the environment variable.
*
* Return: Success: 0
* Failure: 1
