[PATCH 1/2] user32: Fix menu item rectangle calculation in GetMenuItemRect().

[Zhiyi Zhang]

This fixes the menu of BibleWorks 10 not showing up and some todo
in tests.

Sysmenu is in non-client area. And because MapWindowPoints()
should not be used with non-client area coordinates. Doing so
results in wrong coordinates for sysmenu item rectangles.
