Subject: [PATCH 2/2] wayland: Set startup ID from GApplication platform data

The GApplication platform data may contain a startup ID that on X11
is used to set the startup notification ID when activated. Do the
same on the wayland backend to make startup notifications work for
DBus-activated applications where the DESKTOP_STARTUP_ID environment
variable is not set.
