DO NOT MERGE Add mock filegroups to deal with merge conflict problem

This is a preparing CL to cherry-pick netstats jni from git_master to
aosp. Define some mock files to deal with merge conflict problem between aosp
and sc-mainline-prod. The filegroups framework-connectivity-tiramisu-jni-sources
and services.connectivity-netstats-jni-sources is located in
framework/base which do not open for development in sc-mainline-prod.

Bug: 197717846
Test: m libservice-connectivity
Test: m com.google.android.Tethering
Ignore-AOSP-First: this is used to prevent merge conflict.
