True at the end of the user defined late command is no longer needed due...

... to the following change in cobbler: Moved late command post trigger to be after the user added late_commands. This enables us to support reconfiguration of the network with a post command (eg. to enable LACP). Also moved the nopxe post to be after the late command in case an error during the late command halts the install. https://bugs.launchpad.net/openstack-cisco/grizzly/+bug/1171948
