I pushed the patch as ab9de8cfb0525ef43668712ac898707f97f9a620.

I verified that it fixes the immediate problem with fonts in the Guix
manual (#41282) as well as 'guix pack' (#41344).  It should also provide
a decent fallback for cases where the user did not explicitly install
any fonts such as in #41241.

Hoping for angry reports now about why such a poor replacement font was
chosen.  ;-)
