Excluded testSetNetwork test variants from WebView CTS Android 13

Excluded 2 failing test variants as a quick fix:
"android.webkit.cts.PacProcessorTest#testSetNetwork"
"android.webkit.cts.WebViewTest#testSetNetworkAvailable"

They are failing on builders "android-webview-13-x64-dbg-tests"
and "android-13-x64-rel" because network is disabled on the
Android 13 emulator (crbug.com/1368663).
