Set keepalive socket timeout to default value

Fix: 142978377
Test: 1. atest android.net.cts.ConnectivityManagerTest\
         #testSocketKeepaliveLimitWifi --generate-new-metrics 10
      2. atest android.net.cts.ConnectivityManagerTest
      3. manual simulate connection timeout by changing test
         address
