tests: Enable the drive_del test also on s390x

We can use the drive_del test on s390x, too, to check that adding and
deleting also works fine with the virtio-ccw bus. But we have to make
sure that we use the devices with the "-ccw" suffix instead of the
"-pci" suffix for the virtio-ccw transport on s390x. Introduce a helper
function called qvirtio_get_dev_type() that returns the correct string
for the current architecture.
