            Update fontconfig config

This should stop the noise seen with flatpak-module-tools, as
/run/host/font-dirs.xml exists only when running flatpaks or building with
flatpak-builder, but not when building in mock (which does not involve
running flatpak).

Fontconfig error: Cannot load config file "/run/host/font-dirs.xml": No such file: /run/host/font-dirs.xml
