clients: Add screensaver inhibitor client demo

Browse Source 
Derive client from simple-shm and hook up the API defined in
wayland-protocols to allow client screensaver inhibition requests.

v5:
  + Add simple-idle client demo
  + Add command line options to delay creation/destruction of inhibitor
