session: warn about unset WAYLAND_DISPLAY instead of XDG_SESSION_TYPE

XDG_SESSION_TYPE isn't a reliable check for Wayland being present (e.g.
on Ubuntu Touch currently XDG_SESSION_TYPE is "mir" with WAYLAND_DISPLAY
set to "wayland-0" as it also provides Wayland windowing.

Also mention the behavior of defaulting WAYLAND_DISPLAY to "wayland-0"
in case it's not set.
