Initial rewrite of install-iso/Makefile to avoid rebuilds!

Rewrite the Makefile to avoid rebuild of squashfs images,
base filesystem, and redownload of packages for make the core-pkgs.

For now (what is tested): type make and all images will be created
in < 4 minutes (under tmpfs on Athlon 64 X2 5200+ 4GB)
