virsystemdtest segfault on ppc64

[Cole Robinson]

I'm seeing failures building libvirt 6.8.0 rpm on fedora 32, 33, and
rawhide. virsystemdtest is segfaulting on ppc64.

https://kojipkgs.fedoraproject.org//work/tasks/5494/52595494/build.log

The output from the failed tests:
 74/160 libvirt / virsystemdtest                  FAIL           0.44s
(killed by signal 11 SIGSEGV)
