build: Catch and error upon circular task references
If there are circular task references, error on them rather than show
a recursion error. A simple reproducer is:
"""
do_packageswu () {
:
}
addtask do_packageswu after do_image_complete before do_image_qa
"""
into image_types.bbclass. There is code in runqueue to detect these but
we never get that far with the current codebase.
