Bug 8022: Permissions test doesn't check all languages

Add the permissions files for es-ES and nb-NO to the permissions test.

Running xt/permissions.t before the patch leaves out nb-NO and es-ES.
After the patch they are picked up and the test fails correctly
because of the missing permissions described in Bug 7984.
As far as I can tall, all permission files are now picked up by
this test.
