[gtk+] wayland: Use pointer gestures protocol from wayland-protocols



commit 912e79dbe290d6864acaf85174da9a5b6eec30e1
Author: Jonas Ådahl <jadahl gmail com>

    wayland: Use pointer gestures protocol from wayland-protocols
    
    Instead of having our own copy of the pointer gestures XML file, use
    the one installed by wayland-protocols.
    
    Since pointer gestures is an unstable protocol, it went through the
    unstable protocol naming convention changes, which is reflected in this
    commit.
