userns: Convert audit to work with user namespaces enabled
- Explicitly format uids gids in audit messges in the initial user namespace. This is safe because auditd is restrected to be in the initial user namespace. - Convert audit_sig_uid into a kuid_t. - Enable building the audit code and user namespaces at the same time. The net result is that the audit subsystem now uses kuid_t and kgid_t whenever possible making it almost impossible to confuse a raw uid_t with a kuid_t preventing bugs.
