[cheese] Use shoot action when handling the webcam button

[David King <davidk src gnome org>]

commit 6ab3c5248d9564ecc383b6c29cb3bcde7fa7c977
Author: Hans de Goede <hdegoede redhat com>

    Use shoot action when handling the webcam button
    
    Rather then calling on_shoot directly, call the action, so that if shoot
    is disabled, it also cannot be triggered through the webcam button.
