Gabriel Ebner 9fb2c88df4 source-han-*: reduce closure size by 2x
The file name of the installed font was the path returned by fetchurl:
`xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-SourceHanSans.ttc`

This caused the derivation to reference the downloaded font file,
storing the font twice unless you optimise the store (each file is
~150M).
