app-emulation/libvirt: v7.(9|10).0: (temporary) fix cgroup v2 support

Revert an upstream commit that fixed an libvirt_lxc container startup
issue with cgroup v1 layout. The patch in question breaks
systemd-machined integration (at least under cgroup v2 layout).

Le't temporarily revert the commit in question until upstream has found
a proper fix.
