Some time ago, lxc.console was changed to require a device. lxc-start
gained an lxc console logfile argument, but this was not supported
through the container config.
This patch adds the option through container config as 'lxc.console.logfile'.
This allows for instance cloud providers to configure all containers to
log the consoles.
