scripts: don't create pool with deprecated properties

The recent changes to the properties resulted in properties 'name' and
'path' being deprecated in favour of 'pool.name' and 'pool.path'.  Most
references were updated, but a couple were missed.

This patch fixes those missed properties to use the new naming scheme.
