Ignore the P_SYSTEM process flag, and do not request
VM_MAP_WIRE_SYSTEM mode when wiring the newly grown stack.

System maps do not create auto-grown stack.  Any stack we handled,
even for P_SYSTEM, must be for user address space.  P_SYSTEM processes
with mapped user space is either init(8) or an aio worker attached to
other user process with aio buffer pointing into stack area.  In either
case, VM_MAP_WIRE_USER mode should be used.
