[Buildroot] [PATCH 8/8] core/show-info: report image name of filesystems

[Yann E. MORIN]

The rootfses, unlike packages, do not have stampfiles to represent
whether they are built or not. Indeed, we always rebuild the rootfs, and
there is a single step to do.

Hpwever, people (and scripts) who want to report on the build progress,
will want to know whether each rootfs has been built already or not.

Expose in show-info the name of the file that wil contain the rootfs
image.
