printers: Hide header buttons when there's no printer server

Browse source 
There's no reason to "Unlock" the panel and/or "Add" a new printer
if there's no printer server available.

This patch sets the visibility of the "headerbar-buttons" based on
whether the current visible stack page in the panel is the
"no-cups-page".
