[PATCH 2/2] testsuite: Add tests for installer image

[Uladzimir Bely <ubely@ilbers.de>]

The idea is to pass to qemu two wic files (hard drives):
 - sda: empty wic file;
 - sdb: the image with installer.

When run, first boot is done from sdb (since sda is empty), then
installer flashes target image to sda and reboots the system.

Second boot is automatically done from sda drive just written.
