Fix buttonbar and line padding in time&date screen.

The time&date screen uses a custom parent for do_menu(), and doesn't
account for the buttonbar and list line height. Introduce
gui_synclist_set_viewport_defaults() to set those for viewports that are
going to be list parents and use that so that time&date screen doesn't need
to know about buttonbar/line padding.
