vicharak-config: cli: u-boot-menu: Add support for alternative DTBO path

The mainline dtso files compiled into dtbo with a slightly different
manner, where the first fragment is the metadata node.

Previously metadata node was used directly instead of being a fragment
which was not getting parsed by the overlay manager.

Fix this by checking for the metadata property in the first fragment.
