Bug 16497: (follow-up) GET operations require staff access

With the introduction of the /public namespace all other endpoints, the
rest of the endpoints are restricted to privileged users.

This patch makes the GET /libraries and GET /libraries/:library_id
endpoints require 'catalogue' permissions.
