    build: Remove conditional EXIF documentation
    
    EXIF support in Eye of GNOME is conditional and it can be enabled
    by using an option. When shuch option is disabled, documentation
    generation with GtkDoc should exclude EXIF.
    
    This patch disables this behaviour also including EXIF when
    documentation is generated, however a blank page will be
    presented.
