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

Commit 71d35d8940118bc6de6522913fb8c473fa5b2c24 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.
