Redirect qtaguid native call to netd fwmark client

In order to replace qtaguid module with new eBPF network monitoring
module. We firstly move the current qtaguid userspace implementation
into netd and hide the detail from other processes. The current API will
talk to netd fwmark client to pass down the qtaguid related request from
high level framework and netd will use the proper method to complete the
request.

Test: Current TrafficStats CTS tests should not fail.
