Can't move window by drag and drop by using touch screen

[Bin Li]

[Impact]
Users using touch screen could not move windows with 'Drag-n-drop'.
This SRU fixes the issue.

[Test Plan]
1. Install the 22.04
2. Boot and login
3. Open a folder or terminal
4. Drag-n-drop the title bar of nautilus or terminal windows with finger touch
5. Drag-n-drop the title bar of nautilus or terminal windows with the Wacom Pen

Expected: Both finger touch and wacom pen work normally.

Actual: Wacom Pen works normally, finger touch can not move the windows.

[Where problems could occur]
It's a regression of upstream packages, https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/866
