Fix test failure on S image + S module

aosp/2085868 has not included in a tethering train build and it
probably will be included in a T module release. But the test in
that CL has been put to the S MTS test. Thus, fix the test failure
on S image + S module.

Bug: 233019430
Test: atest CtsNetTestCasesLatestSdk:android.net.cts\
      .ConnectivityManagerTest#testUidsAllowedOnRestrictedNetworks
      on the S image + S module device.
