init.rc: remove bg_non_interactive cgroup 

We have seen cases when threads in this cgroup not scheduled for more than
a few seconds in heavy workload situation and causing device freeze.
In Linux, multiple threads placed in ROOT cgroup cause the CPU resource to
be split per thread, rather than per group.
Currently we have many threads in ROOT cgroup, which makes threads in
bg_non_interactive cgroup to have "tiny" CPU resource other than 5%
quota defined.
