WifiNetworkFactory: Stop restricting peer to peer API network callback

Setting the requestorUid/requestorPackageName on NetworkCapabilities
ensures that only the requesting app gets notified when the network is
connected. However, other apps can find this network using getAllNetworks(),
so obfuscating it via callback is not very useful.

Also, helps system apps to monitor for peer to peer connection.
