[ACT][PATCH 1/2] UBUNTU: SAUCE: ubuntu_kernel_selftests: properly disable memory-hotplug

[Krzysztof Kozlowski]

For arm64 the mem-on-off-test.sh from memory-hotplug was disabled by
removing the executable bit.  However this started failing recently:

    # selftests: memory-hotplug: mem-on-off-test.sh
    # Warning: file mem-on-off-test.sh is not executable, correct this.
    not ok 1 selftests: memory-hotplug: mem-on-off-test.sh

Disable the test just like in other cases - by removing it from
Makefile.
