[libvirt PATCH] apparmor: Allow running /usr/libexec/qemu-kvm

Distros that use AppArmor, such as Debian and Ubuntu, install QEMU under /usr/bin/qemu-system-*, and our AppArmor profile is written with that assumption in mind. If you try to run the RHEL or CentOS version of libvirt and QEMU inside a privileged container on such distros, however, that will result in an error, because the path /usr/libexec/qemu-kvm is used instead. In particular, this prevents upstream KubeVirt releases (which are based on CentOS) from running on Debian/Ubuntu nodes. See https://github.com/kubevirt/kubevirt/pull/8692 and the issues referenced therein for additional details.
