demos: Fix cube ActualTimeLate function
The ActualTimeLate function in cube.c is supposed to check if a
VkPastPresentationTimingGOOGLE structure indicates that the
presentation happened within a refresh-cycle duration of the
desired presentation time.
However currently ActualTimeLate will always return false, because
it is calculating the presentation deadline as `actual + rdur`.
This change calculated the presentation deadline as
`desired + rdur`.
