Subject: [RFC PATCH 59/77] tests: metadata: Add a test for addon without root node

The root device-tree node is no more mandatory for addons.

Indeed, addons can be composed of only orphan nodes without any needs
for the root device-tree node presence.

Add a test related to addon dts and dtb without root node.
