ipc/shm.c: check for overflows of shm_tot
shm_tot counts the total number of pages used by shm segments.
If SHMALL is ULONG_MAX (or nearly ULONG_MAX), then the number can
overflow. Subsequent calls to shmctl(,SHM_INFO,) would return wrong
values for shm_tot.
The patch adds a detection for overflows.
