Switch to packages structure.

The various build scripts are scattered around in multiple
places. This make it hard for contributors to understand what they
need to modify.

Most GNU Boot users are interested in running GNU/Linux or BSD
operating systems. And the way to install software on these
operating systems is through a package manager. So most users and
contributors already know the package manager abstraction.

So using that abstraction makes it easier to find where things are.

The scripts to install dependencies don't really fit the new structure
but for now we move them in to make sure that everything works
fine. This could be fixed later on and migrated to a single
dependencies packages by auto-detecting the distribution with
/etc/os-release.
