Add constructor which used by Android T CTS

aosp/2241257 and aosp/2241058 are included in the mainline train
release and it causes the T device can’t pass CTS-13_R2/CTS-13_R3.
It’s because some parameters of the constructor have been removed.

Add it back to keep backward compatibility.

Test: 1. atest CtsNetTestCases:android.net.netstats.NetworkTemplateTest
      2. CTS-13_R3
