This removes the possibility of passing in arbitrary input data. We
now restrict ourselves to explicitly specified files/directories or
a base tree given by its pipeline id.
This drops the tar/tree stages/assemblers, as the tree/untree ones
are implicit in osbuild, and if we wish to also support compressed
trees, then we should add that to osbuild core as an option.

By default the whole image file is attechd to the loopback device, but
we want to only attach a slice, namely individual partitions.
This is a noop, just adds the parameters to the helpers.

We want to copy the contents of a directory to another, the correct
syntax for that is `cp -a src/. dst`. I was not aware of this beauty,
so the previous patch simulated the functionality in python code.

In the simplest case we don't need to make an image, a filesystem tree
will do. Also support using such a tree as input for further pipelines
through the untree stage.
