Enable native_bridge_support for libprocessgroup

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).
