[RFC PATCH 10/14] package_ipk/deb/rpm: Drop recursive do_build task dependencies

["Richard Purdie" <richard.purdie@linuxfoundation.org>]

This is a controversial change which removes the recursive dependencies
from the do_build target of packaging tasks of recipes.

Currently this means when you "bitbake <image>" or "bitbake <recipe>",
the packaging tasks run for all packaging backends enabled for all recipes
in the dependency chain. The same therefore then applies to images.

We don't actually need that, it is a convinience thing. Removing it
massively simplifies the task graph and causes much fewer tasks to execute
in many common scenarios. It also means less sstate is fetched for
example when building an image.

This means when building a recipe all package formats would be built
but when building an image, only the format used by the image would be
generated. This should be an improvement in most cases but some CI systems
may need to be explict about what they're building.
