P21: enable throttle background group at 5%

Browse source 
Right now we have many groups due to uclamp setup, and this would
potentially create interesting fairness between groups.

Ultimately we want only a system group and a background group for
cpu.shares, which would achieve after b/182509410 resolved.

Test: boot and check setting
