Arian van Putten a48047a755 nixos: Add test that demonstrates how to use nesting.clone
This is actually very useful. Allows you to test switch-to-configuration

nesting.children is still currently still broken as it will throw
away 'too much' of the config, including the modules that make
nixos tests work in the first place. But that's something for
another time.
