[PULL 08/24] iotests.py: rewrite default luks support in qemu_img

[Hanna Reitz <hreitz@redhat.com>]

From: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>

Move the logic to more generic qemu_img_pipe_and_status(). Also behave
better when we have several -o options. And reuse argument parser of
course.
