Wei Wang 40267986da libcutils: remove schedgroup
After removing bg_non_interactive cgroup, there is only a ROOT cgroup.
This CL removes the no-op trying to set cgroup.
It also removes the attempt to open non-exist bg_non_interactive cgroup.

Bug: 36649832
Test: marlin boosts and cgroup ROOT task looks normal

Isaac Chen 795267d4c7 Removed cpusets/schedboost build time dependency.
These two Soong product_variables were usually controlled by
ENABLE_CPUSETS and ENABLE_SCHEDBOOST in BoardConfig.mk. This change
turns the build time variables into runtime decision by checking if
a special file, "tasks", can be found under the mount points,
/dev/cpuset and /dev/stune, for cpusets and schedboost, respectively.

That special file only exists when the corresponding Linux kernel
configurations, CONFIG_CPUSETS and CONFIG_SCHEDTUNE, are set.

Bug: 34726944

Test: Tested on Sailfish with following configurations
          neither cpuset nor schedtune enabled in the kernel
          cpuset enabled, but schedtune disabled in the kernel
          both cpuset and schedtune enabled in the kernel
