qemu.tests.multi_disk: Tweak the config file of virtio_scsi_variants

Use the unified configs (scsiid=>unit, lun=>port) and store the images
in the usual location. The location '/tmp/%s' was used before because
python was unable to execute that long command and this prefix shorten
it significantly. Now autotest supports the way to deal with long
commands so we can finally store the images in the right location.
