Fix libvirtd memory leak in CentOS Stream 8

All nova images were rebuilt for CentOS Stream 8. Images for other
distributions are unmodified because they are not affected.

The qemu-kvm package is pinned to the latest version able to live
migrate from qemu-kvm-6.2.0-20.module_el8.7.0+1218+f626c2ff in the
stackhpc kolla fork [1].
