lxc-checkpoint: close stdout/stdin when daemonizing

Browse Source 
If we don't close these running lxc-checkpoint via:

ssh host "sudo lxc-checkpoint ..."

just hangs. We leave stderr open so that subesquent errors will print correctly
(and also because for whatever reason it doesn't break ssh :).
