This fixes a regression introduced in commit 7171d824.

"guix-emacs.el" may be used just for "instructing" Emacs where to find
Emacs packages installed with Guix, so it should have as few
dependencies as possible.

Make a root 'guix-buffer-define-interface' macro. It should generate a
common code for any type of interface. Inherit 'guix-info-define-interface'
and 'guix-list-define-interface' from it. They should provide a general
'info'/'list' interface for any data. Finally, make

packages and generations, and inherit 'guix-ui-info-define-interface' and
'guix-ui-list-define-interface' from it.
