[platform] CLIHandler: Socket creation failed

[Patrik Karlström]

I'm packaging a platform application as an ubuntu snap without the network
interface, https://snapcraft.io/docs/network-interface
The app works as expected but one is greeted with the error below on start.

Is there a way to disable the network lookup?
