Convert statsd_test and statsd_benchmark to proto lite

libplatformprotos for the device is compiled using proto lite, and
statsd_test and statsd_benchmark have protos that reference the
libplatformprotos.  With protobuf 3.9.1 compiling a full proto
against a lite proto doesn't work.  Convert them to lite.  Requires
adding the protobuf internal protos to the sources,
libprotobuf-cpp-lite does not contain the compiled version of
field_options.proto.
