Fix proto invalid write type

While dumpProtoLocked is called, InvalidProtocolBufferException
occurred because types are mismatched between platform side and
module side.

netstats.proto was moved into connectivity module, both the
platform(incident.proto) and the module uses protoc-gen-javastream
to generate the Java classes from it. It should be fine since
platform includes the source of the proto, and jarjar the generated
classess in the module to avoid conflict with platform.

Bug: 218566849
Test: adb shell incident 3001
      adb shell dumpsys netstats --proto
