kilpilainen 02f8744a48 Use all-scroll instead of fleur xcursor shape for window dragging ...

When there are no xcursor themes available, Wayland uses its own built-in shapes [1].
Wayland (and thus to extend wlroots) is based on the XDG's cursor spec [2],
which itself is based on CSS' [3][4], neither of which define `fleur` shape. So dwl,
without any external themes, falls back to `default` shape when dragging a window.
There is `all-scroll` shape that is being symlinked to (or vice versa) by `move`,
`dnd-move`, `grabbed` and `fleur` shapes by various themes.

Since `all-scroll` is being symlinked to anyway, and has been part of all relevant
specs as the shape for this use case for a very long time now, use it instead.
