libprocessgroup: ensure schedboost_enabled is true with uclamp

Browse source 
In the current state, schedboost_enabled() is true if and only if
schedtune is in use. As a result, all tests conditioned by
schedboost_enabled() will be skipped on devices using uclamp since it is
and extension of the CPU controller.

Fix this by making schedboost_enabled() return true if either schedtune
or the CPU controller is enabled.
