They can find the font packages I install with Guix, but not the
hard-coded PostScript fonts.

I looked more closely, and Guix applications can no longer see *any*
fonts from Debian.

Confirmed. fc-cache exited successfully when I removed those directories.

The only differences, after running `fc-cache -rfv`, are the differing
store paths of the hard-coded gs-fonts package.

Another thing I noticed is that I can do `fc-cache -rfv /usr/share/fonts
&& fc-list`, and the hundreds of fonts found in that directory are *not
shown* in fc-list, but that's the same as on the master branch.

So, I'm still not sure what the difference is.
