[REVIEW][PATCH 05/11] shm: Move struct shmid_kernel into ipc/shm.c

["Eric W. Biederman" <ebiederm@xmission.com>]

All of the users are now in ipc/shm.c so make the definition local to
that file to make code maintenance easier.  AKA to prevent rebuilding
the entire kernel when struct shmid_kernel changes.
