wibox_position_update(): Skip wibox if wibox.screen is nil 

If a wibox's screen is set to nil, this is reflected by setting the screen
struct member to SCREEN_UNDEF.
SCREEN_UNDEF is defined as -1. If we allow such a wibox in
wibox_position_update(), bad things will happen (globalconf.screens[-1]).
