klte-common: Don't set swappiness to 100

* Don't do this, it destroys performance!
 * Android uses memory cgroups to manage ZRAM. Memcg allows you to
   view stats as well as set options like swappiness on a per-cg
   basis. In the main init.rc, the background cgroup already has it's
   swappiness set to 100. This patch sets it globally, which will
   aggressively swap even foreground tasks into ZRAM which has a huge
   amount of overhead.
