PM / sleep: Skip OOM killer toggles when kernel is compiled for Android

Browse source 
Android devices use LMK algorythms, so there's no
reason to disable and enable the OOM killer when entering and exiting
suspend.

This is a fixed version of https://github.com/YaroST12/VIOLENT_kernel/commit/86e59a93b2ef
