bug#45845: emacs-doom-modeline: Some icons are missing

[Wilko Meyer]

Hi Guix,

This issue still persists on:

guix d884fc9
GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.37,
cairo version 1.16.0)
doom-modeline 20230624.1524

In addition to that, all-the-icons-install-fonts doesn't seem to fix
the missing icons in doom-modeline, even though the installation doesn't
run into erroneous behaviour during install and all-the-icons.ttf is
present afterwards:

(~) λ fc-list | grep all-the
/home/wilko/.guix-profile/share/fonts/all-the-icons.ttf: 
all\-the\-icons:style=Regular
/run/current-system/profile/share/fonts/all-the-icons.ttf: 
all\-the\-icons:style=Regular
/home/wilko/.local/share/fonts/all-the-icons.ttf: all\-the\-icons:style=Regular

I assume that the latter issue may be more on the emacs-all-the-icons
side of things, and not particular emacs-doom-modeline related.
