Fixes &lt;https://issues.guix.gnu.org/68848&gt;.

The current implementation of the home-dotfiles-service-type contradicts
the Guix manual.  This patch properly implements both the plain and Stow
dotfiles directory layouts.

It does so by refactoring home-dotfiles-configuration adding a new
packages field to support GNU Stow's users workflow and introducing
a new layout field to switch between the two directory layouts.

* gnu/home/services/dotfiles (home-dotfiles-configuration): Migrate to
(gnu services configuration);
[packages]: new field;
[layout]: new field;
(strip-stow-dotfile): new variable;
(strip-plain-dotfile): new variable;
(home-dotfiles-configuration-&gt;files): use the new fields;
[directory-contents]: allow for
selecting a subset of application dotfile directories;
* doc/guix.texi: document the new layouts.
