no need to call 'gnome-update-wallpaper-cache' anymore

[Tim Lunn]

These days, g-s-d/u-s-d are running in the installer session, so we don't need to call a binary that forces a redraw of the background just so we can copy the cache across.

Once these calls are dropped from ubiquity we can also drop the corresponding binary from g-s-d and u-s-d.
