    lxc: controller: Fix container launch on cgroup v1
    
    With cgroup v1 I'm seeing LXC container startup failures:
    
    $ sudo virt-install --connect lxc:/// --name test-container --memory 128
    --boot init=/bin/sh
    
    Starting install...
    ERROR    error from service:
    GDBus.Error:org.freedesktop.machine1.NoMachineForPID: PID 2145047 does
    not belong to any known machine
    
    libvirt 7.0.0 works but 7.1.0+ does not. The root error seems to predate
    that, showing up in syslog, but commit 9c1693eff made it fatal:

         vircgroup: use DBus call to systemd for some APIs
    
    The error comes from virSystemdGetMachineByPID. The PID that shows up in
    the above error message does not match the leader PID as reported by
    machinectl.
    
    This change fixes the error. Things seem to continue to work with
    cgroupsv2 after this change.
