Move image recipes away from meta packages

The current image recipes rely on a bunch of meta packages to fetch the
appropriate packages.

This approach does not scale well: every time we want to add a new image
type we would need to create a new recipe and a new package, filling the
archive with meta packages that may differ only for a couple
dependencies and making the whole flow more cumbersome.

Current recipes also do not exclusively rely on these meta packages, as
they often explicitly list some direct package dependencies already.

Putting the package dependencies directly in the recipes and dropping
the meta package would provide a smoother workflow.

This patch do not use any Apertis-specific meta package but instead
directly list the desired packages in the image recipes.
