Nafees Nastaleeq for Urdu

Well, "Urdu Nastaliq Unicode" seems added by Mandriva guy at c26344ecfc1d3b85671f5d948a10d5cc27c21c2f. you may need to talk to him about this change perhaps.

FWIW this is correct metadata for Urdu Nastaliq Unicode:

The glyph coverage for Urdu looks like Nafees Nastaleeq is better than Urdu Nastaliq Unicode at least. though there seems a lot of fonts that support Urdu in the world, DajaVu, Kacst, Nafees, and PakType, and maybe more.
I can't figure out this is really better choice for Urdu and can't settle the kind of this issue so I'm always suggesting to have own recipes to give it a priority instead of changing the default font here because this is sort of subjective matter.

Hi Akira,

Thanks for your informative reply! Following your advice, we fixed this in Ubuntu by adding an own recipe.
