description:
Adjust the default fontconfig fonts.conf to avoid selecting bitmap
fonts included as part of X11 that are also included as scalable fonts
as part of macOS.

Many websites will attempt to select these fonts, which results in
very strange, poor quality rendering.

This should keep legacy X11 applications that want the old "Helvetica"
and "Times" fonts working, but prevent them from being selected by
applications that want scalable fonts.

It should not prevent "Helvetica" or "Times" from being selected
if the user installs a scalable version.
