chgserver: store csystem separately

Previously, the "system" channel is inside the ui object. In the future, chg
will let dispatch to create a new ui object from scratch, to maximize
compatibility. And chgserver will use a "uisetup" like an extension to wrap
ui.system. To be able to do that cleanly, the system channel needs to be
accessed directly.
