libc/ipc: Allow architectures to define their own __IPC_64 macro
New architectures don't define ARCH_WANT_IPC_PARSE_VERSION in their kernel.
This means that every cmd passed to semctl,msgctl and shmctl is IPC_64 by
default. For these architectures we need to define __IPC_64 as 0. Existing
architectures are not affected by this change.
