wayland: Use CSS/freedesktop cursor name "default" as a fallback

Browse Source 
The "left_ptr" name is an X11 thing, and there's no guarantee that
Wayland cursor themes contain it. In particular, GNOME's Adwaita theme
as of version 46.beta only contains the CSS/freedesktop names.

To test, either move one of the known cursors out of the way, or edit
the switch statement above to use a wrong name for one of them.
