Subject: image: T4516: support for interoperability of legacy/new image tools

This commit allows management of system images with either new or legacy
tools: 'add/delete/rename system image' and 'set default' are translated
appropriately on booting between images with the old and new tools.
Consequently, the warning of the initial commit of T4516 is dropped.
