Yup. And the path that other distros as well as upstream QEMU use
doesn't exist, so we are forced to have this special handling.

  $ podman run --rm quay.io/centos/centos:stream8 \
    sh -c 'yum install -y qemu-kvm-core && rpm -ql qemu-kvm-core' 2>&1 \
    | grep -E '/usr/libexec/qemu-kvm|/usr/bin/qemu-system-x86_64'
  /usr/libexec/qemu-kvm

  $ podman run --rm quay.io/centos/centos:stream9 \
    sh -c 'yum install -y qemu-kvm-core && rpm -ql qemu-kvm-core' 2>&1 \
    | grep -E '/usr/libexec/qemu-kvm|/usr/bin/qemu-system-x86_64'
  /usr/libexec/qemu-kvm

Luckily, now that thanks to your report I've cleaned things up it's
not actually that bad :)
