[PATCH] image.bbclass: use prependVarFlag for postfuncs

[PATCH] image.bbclass: use prependVarFlag for postfuncs

[Ed Bartosh]

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

[YOCTO #11372]

Thanks to Ola Nillsson for the idea.
