From: Philippe Mathieu-Daudé <philmd@linaro.org>

Add the generate_pkglist() helper to generate a list of packages
required by a distribution to build QEMU.

Since we can not add a "THIS FILE WAS AUTO-GENERATED" comment in
JSON, create the files under tests/vm/generated/ sub-directory;
add a README mentioning the files are generated.
