[PATCH] winex11.drv: Add a delay on FocusIn/NotifyUngrab before grabbing the cursor.

[Rémi Bernon]

Since 92177b0b161e91f1d609615d89d8e3199feea33f we retry grabbing the
cursor with the last clipping rectangle as soon as the WM releases the
keyboard. However it sometimes messes up with the Shell that expects
to be able to grab the cursor before opening activity view.

Without this, it can be hard to trigger the GNOME Shell activity view
by pressing the Super key while a Wine window is active.
