Rather than copying images, use the snapshot option to qemu. This fixes a regression caused by the recent runqemu changes where the wrong images were being testes since the image is copied without the qemuboot.conf file. This means the latest image is found by runqemu rather than the specified one, leading to various confused testing results. It could be fixed by copying more files but use snapshot mode instead.
