Update and clean up the fontconfig files

Update and clean up the fontconfig files

1. Add Droid Arabic {Kufi,Nashk},Droid {Sans,Serif} Thai, SIL Absinnica fonts
   to the alias list for serif, sans-serif and monospace in local.conf

Change-Id: I08ff46eb5267cc564e01b009d5cc7a3422ec91d2

2. Do not install 60-latin.conf, 65-nonlatin.conf, 65-fonts-persian.conf. They have a long list of fonts that we don't have on CrOS or we already list in local.conf in the order we want them to be in.

  Add Lohit Oriya and Lohit Malayalam to the list of fonts for
serif, sans-serif and monospace in local.conf.

Change-Id: If22e61763d9f2f85942b200c4fcfa566a9a42852

3. Add an orthography patch to zh_tw.orth and zh_hk.orth to remove a couple of very rarely used characters. This (along with #2 above) is an effort to 
block PMingLiU from popping up at the top of the list when a font covering any Chinese character is requested. It should not, but somehow it does.

Change-Id: Id69e564ff1890792798b389cf3ac725c5b6970b8

4. Put 'Song ASC' for serif instead of Droid Sans Fallback. 'Song ASC' is a serif font.

BUG=1175
TEST=Go to ar.wikipedia.org and make sure that there's no empty box any more.

Hints are on without this file so this won't do anything. It is okay to have
this file as this is what the system is (and should be) doing. Let's hope it
helps people more in the future that is confuses people.

I'm curious why for sans the Nanum font is after Droid Sans Fallback (as
compared to serif where the font is before).

Oops. I meant to add a comment on that, but forgot. 

That is because I don't want Chinese characters in NanumGothic to trump Chinese
characters in Droid Sans Fallback. NanumGothic has Chinese characters (~ 4800 of
them) while NanumMyeongJo does not. 

It'd be easier for us if either of this is the case:

1) NanumGothic does not have any Chinese characters
2) Droid Sans Fallback does not have any Korean characters.

Then, regardless of which order I use to put them in, Korean characters will
come from NanumGothic (superior to those in DSF) and Chinese characters will
come from DSF. 

I'm considering removing Korean characters from Droid Sans Fallback on ChromeOS.
