winex11.drv: Send HTMENU instead of HTCAPTION to query window activation.

Commit 71d35d89 broke the way WM_TAKE_FOCUS protocol is implemented: WM_MOUSEACTIVATE now replies MA_NOACTIVATE by default when using HTCAPTION. We use the WM_MOUSEACTIVATE -although Windows does not- regardless of the way focus is changed to check whether a window wants focus, and Windows sometimes changes focus regardless of the message reply. Steam and the Wine system tray are affected for instance. Signed-off-by: Rémi Bernon <rbernon@codeweavers.com> Signed-off-by: Alexandre Julliard <julliard@winehq.org>
