This patch adds the "qemu" namespace package to the $build/tests/venv directory. It does so in "editable" mode, which means that changes to the source python directory will actively be reflected by the venv. This patch also then removes any sys.path hacking from the avocado test scripts directly. By doing this, the environment of where to find these packages is managed entirely by the virtual environment and not by the scripts themselves.
