[PULL 50/56] iotests/image-fleecing: proper source device

[Hanna Reitz <hreitz@redhat.com>]

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

Define scsi device to operate with it by qom-set in further patch.

Give a new node-name to source block node, to not look like device
name.

Job now don't want to work without giving explicit id, so, let's call
it "fleecing".
