Controllers listed in cgroups.json file might fail to mount if kernel is
not configured to support them. We need a way to indicate whether a
controller was successfully mounted and is usable to avoid logging errors
and warnings when a controller that failed to mount is being used. Add
flags bitmask to cgrouprc controller descriptor and use a bit to indicate
that controller is successfully mounted. Modify cpusets_enabled() and
schedboost_enabled() functions to use this bit and report the actual
availability of the controller.

Android build system added support for building translated binaries
used on natively bridged targets (arm on x86 for example).
However in order to avoid building unnecessary binaries and libraries
for such architectures most modules do not support native bridge by default.
All needed modules have to explicitly indicate if they may be used as part
of translated binary build.
This change enabled native bridge support for libprocessgroup modules
needed by libutils greylisted library (available for apps targeting
Android version < N).
