Dudemanguy 61aecfabfd vo_dmabuf_wayland: correct full window size calculation 
The current calculation makes the implicit assumption that the margins
on both sides are always equal (the 2 times multiplication). This isn't
true though. For example, a 720p video fullscreened on a 1680x1050
display will have a top margin of 52 but a bottom margin of 53. The
current calculation just multiplies 52 by 2, so it's off by one. Fix
this by adding together all the margins together (left + right or top +
bottom) then adding that to the dst window size (width or height). This
way, we get the full size of the window for the viewport. Fixes #12554.
