The machine name already contains the words "ccw" and "virtio", so
using "VirtIO-ccw" in the description likely does not really help
the average user to get an idea what this machine type is about.
Thus let's switch to "Virtual s390x machine" now, since "virtual
machine" should be a familiar term, and "s390x" signals that this
is about 64-bit guests (unlike S390 which could mean that it is
31-bit only).
Also expand "v" to "version, since this makes it easier to use
this macro also with non-numeric machine names in downstream.

Do we foresee any s390x machines that don't default to ccw virtio
devices in the future?

I don't think so. And if we ever get another type of para-virtualized
machine, we still can change the description again to be more specific to
distinguish them.

Thanks!
