Make sure a wibox does not display garbage when made visible 

This moves the call to wibox_draw() into wibox_map() which fixes garbage
being displayed if a wibox is made visible by setting its .visible.

Since wibox_draw() already calls simplewindow_refresh_pixmap(), that call is
dropped. Because wibox_need_update() just makes sure wibox_draw() is later
called, we can replace the call to wibox_draw() by this call. This should avoid
superflous updates.

Found by lua code like this:

local w = wibox({ position = "floating", bg = "#ff0000" })
w.visible = false
w.screen = 1
<do some other stuff>
w.visible = true
