userns: use union in {g,u}idmap struct
- Add a struct containing two pointer to extents and wrap both the static extent array and the struct into a union. This is done in preparation for bumping the {g,u}idmap limits for user namespaces. - Add brackets around anonymous union when using designated initializers to initialize members in order to please gcc <= 4.4.
