x11-fonts/fontconfig: update to 2.13.92

Fontconfig 2.13.1 generated .uuid files in the fonts directory which where
not properly registered to the packages. To clean them up, please execute the
following command:

find %%LOCALBASE%%/share/fonts -type f -name .uuid -delete

By switching to this RC, the dependency on libuuid can be droped again, and the
issue of registering uuid is moot.
