keyboard: Disable emoji support on X11

Unlike regular keys that generate key events from a virtual device,
emoji keys rely on the input method to insert the character. However
as the compositor cannot inject IM events into ibus, this only works
in the shell's own entries on X11.

We shouldn't expose mostly broken functionality to the user, so limit
the feature to the wayland session.
