Fix panic on creation of zero-len shm segments.
Attempting to create a zero-len shm segment causes a panic since we
try to allocate a zero-len filemem region. The existing code had a
guard to disallow this, but the check didn't encode the fact that
requesting a private segment implies a segment creation regardless of
whether IPC_CREAT is explicitly specified.
