[syslinux-iso] create root-image tree in two steps

First install {base} group, then install rest of packages listed
at in packages file.
In this way, ensure a fully base system installed first,
avoinding errors from install scriptlets of rest of packages.

(currently there is no issue with packages listed on packages files,
but if some add more packages to customize the iso will see errors)
