tests: Update capabilities for QEMU 8.1.0 on s390x

The existing capabilities were generated against a build made
quite early in the QEMU 8.1.0 development cycle. Update them
to match the final release.

A notable effect of this is that the recently introduced
s390-usb-model test now passes instead of failing: QEMU 8.1.0
enables several new devices on s390x, including the qemu-xhci
USB controller.

There's a small amount of additional churn caused by the fact
that the machine on which I have generated these capabilities
is apparently slightly less fancy than the one used originally.
