[bug#51962] python-libvirt build failure on core-updates-frozen

[Jack Hill]

Hi Guix,

python-libvirt currently (commit dab4ce01044b2d960da7375735e9543a259f97d3) 
fails to build for me with:

Updating python-libvirt to the latest release, 7.9.0 solves the problem. 
The only dependent package, virt-manager, as reported by `guix refresh -l` 
builds and works (I was able to connect to the graphical console of a VM 
running on a remote host). Tested on x86_64-linux.

Best,
Jack
