classes/populate_sdk_ext: ensure tasks to build the image are included
If you build an extensible SDK for an image and IMAGE_FSTYPES includes
"live" then the extensible SDK will fail to install with a bunch of
unexpected task execution errors, matching the missing items required to
build the live image. The issue was we were still depending on do_rootfs
rather than do_image_complete. The fix was slightly more complicated
than just changing the task name as do_image_complete's dependencies are
in the form of dependencies on tasks within the same recipe (represented
in the "deps" varflag rather than the "depends" varflag).
Fixes [YOCTO #9826].
