ivi-shell: Temporary fix: Send keyboard events to clients who binds wl_keyboard.

This is a temporary solution to send keyboard events to clients for
CES2016 demo. This shall be resolved by using ilm keyboard focus later.
This doesn't affect current wayland application who uses
wl_pointer/touch and wl_keyboard.
