[configs/releng] Add new build mode: all

This mode allow to build all 6 ISOs in just one step if build type is <all>.
So "build.sh build all all" -> (single-i686, single-x86_64, dual) X (netinstall, core).

Note that the <purge> command is executed between each build step to save space,
so do not use this mode if you want to keep all temporal files in work_dir.
