Manfred Spraul 1376327ce1 ipc/shm.c: check for integer overflow during shmget.
SHMMAX is the upper limit for the size of a shared memory segment, counted
in bytes.  The actual allocation is that size, rounded up to the next full
page.

Add a check that prevents the creation of segments where the rounded up
size causes an integer overflow.
