    image.bbclass: use prependVarFlag for postfuncs
    
    It would be possible to achieve any order of calling functions if
    prefuncs are added with appendVarFlag and postfuncs with prependVarFlag.
    Then image_X.bbclass can add code with either pre/post-funcs or
    do_image_x_append or _prepend.
    
    The execution order would be:
    
    image_X prefuncs
    image prefuncs
    do_image_X_prepend from image_X.bbclass
    do_image_X from image.bbclass
    do_image_X_append from image_X.bbclass
    image postfuncs
    image_X postfuncs

    Thanks to Ola Nillsson for the idea.
