land: Give additional cores to background cpuset

Browse source 
* When a device with hundreds of apps is booted up, hundreds of
   apps will spawn their BOOT_COMPLETED receivers which start
   up their background initialization services. Since only one
   core is allowed for these processes, the time for all these
   services to complete is extremely long.
 * To improve this, allow three cores for background processes,
   keeping the fourth for idle wakeups. This ends up producing
   a better thermal profile for the device as well, since the
   small cores are not the aggressor on this SoC.
