rootdir: init.rc: remove audio app/sys groups, merge to fg

With this change, the audio rr/fifo threads will just run in
the fg cgroup.

Also, the RR budget for the apps fg/bg threads has been bumped
to 80%. Ideally, the bg budget would be much smaller but there
are legacy libraries that seem to be very sensitive to this so
for now keep it at this value.
