zero-possible test in test_030_mmap_min from ubuntu_qrt_kernel_security failed with ARM64k

[Po-Hsu Lin]

Issue spotted after bug 1931393 has been fixed with https://git.launchpad.net/qa-regression-testing/commit/?id=7e4af649e18218e8ce0afeba4a6e642db80cbab4

The zero-possible test in test_030_mmap_min will fail with:
$ sudo ./zero-possible 32768
Testing lower 32768 bytes in 65536 byte chunks: pass (could not allocate memory)
Testing 65536 byte chunk above 32767: pass (able to allocate memory)
$ echo $?
0

However this is expected to fail:
  # Test that zero is still possible
  self.assertShellExitEquals(1, ["./zero-possible", '%d' % (mmap_limit)], msg="Unable to allocate zero-page when mmap_min_addr set to 0!\n")

And thus causing the test_030_mmap_min to fail.
