compositor-wayland: use image loading code from shared/

Function weston_load_image() was deleted in f02a649a but the wayland
backend was not adapted to the new interface. This probably went
unoticed because the prototype for the missing function was not deleted
from compositor.h so the backend would compile without warnings.
