bug#38998: emacs-treemacs missing icons

[Christopher Howard]

Hi, I cherry-picked emacs-treemacs and emacs-treemacs-extras from Guix
master. emacs-treemacs mode runs in Emacs, but the icons are missing,
and Message buffer is filled with messages like "Cannot find image file
‘/home/christopher/.guix-profile/share/emacs/site-
lisp/icons/default/root.png'". These icons do not seem to be in the
emacs-treemacs or emacs-treemacs-extras store directories after I build
the packages. I haven't been able to figure out yet what other package
is required to get these icons.
