Move the user and user-session keyrings to the user_namespace struct rather than pinning them from the user_struct struct. This prevents these keyrings from propagating across user-namespaces boundaries with regard to the KEY_SPEC_* flags, thereby making them more useful in a containerised environment. The issue is that a single user_struct may be represent UIDs in several different namespaces. The way the patch does this is by attaching a 'register keyring' in each user_namespace and then sticking the user and user-session keyrings into that. It can then be searched to retrieve them.
