allow archs to define IPC_STAT, propagate time64 bit to other macros
to make use of {sem,shm,msg}ctl IPC_STAT functionality to provide
64-bit time_t on 32-bit archs, IPC_STAT and related macros must be
defined with bit 8 (0x100) set. allow archs to define IPC_STAT in
bits/ipc.h, and define the other macros in terms of it so that they
all get the same value of the time64 bit.
