testing: Switch to Debian based guest images

Instead of extracting a downloaded Gentoo filesystem tree into a file
containing a reiserfs filesystem, create an ext3 filesystem inside a
sparse file, mount it and debootstrap an up-to-date Debian system. Use
this image as base for all UML guest images.

Also, drop support for the various consoles and use xterm
unconditionally.
