MGS-3627 [#imx-911] "Could not open egl display" when run monkey test case for long time.

The root cause is that each time an application runs, the gpu driver will map reserved memory 128M to
the application virtual memory space, which means it need the system have at least 128M physical memory available,
otherwise the shmem_zero_setup will fail. Add MAP_NORESERVE flag to fix this problem.
