Update capabilities for QEMU 8.1 on s390x, add a new capability

Is this really something that should be enabled unconditionally on all
s390x guests, or should it be configured with some domain xml? If
there's ever a case where an s390x domain would want this disabled, I
think it would have to be configurable. Also, if there is any situation
where a domain on a different architecture might want to enable this,
that would also require some kind of configurability. At minimum it
seems to me that the commit log should have a lot more justification for
why this approach is justified.

Jonathon,
thanks for your feedback.
I am unsure where to located such a configuration option in the gust
domain XML.
A few thoughts:
1) introduce a new emulator-options element in devices and a run-with
child element with a parameter async-teardown, e.g.
...
<devices>
<emulator>/usr/lib/bin/qemu</emulator>
<emulator-options>
<run-with async-teardown='on'/>
</emulator-options>
</devices>
...
2) introduce a new run-with element with a parameter async-teardown in
domain, e.g.
<domain>
...
<run-with async-teardown='on'/>
...
</domain>
Any ideas and suggestions are welcome.
