Fix template for test network needs fine location permission

Browse Source 
For a template with MATCH_TEST, since the wifi network key is
just a placeholder to identify a specific test network, it is
not related to track user location. Hence the check is not
really needed.

Test: 1. atest NetworkStatsIntegrationTest with use location turned off
      2. atest FrameworksNetTests:android.net.connectivity.com.android.server.net.NetworkStatsServiceTest
Fix: 280686048
