[Bug 1270647] [NEW] Remove WenQuanYi as preferred font for 69-language-selector-zh-{hk, mo}.conf

[Abel Cheung]

Public bug reported:

Currently the only font in Ubuntu supporting (or close enough) Hong Kong
Supplementary Character Set is Uming HK. WenQuanYi was claiming it
supports zh-hk, but in reality it is done with fontconfig deceiving.

In HKSCS charset definition dated 2004, there are 4941 characters.
Somehow, fontconfig only checks less than half of them, around 2213 or
so. WenQuanYi Zen Hei included only those checked glyphs in fontconfig
to claim it's done (at least according to the latest published version
dated 2010-03-12). In particular, there should have been around 1700
characters in CJK extension B. WenQuanYi only has one single glyph in
this range, which is also exactly the only one checked by fontconfig for
zh-hk support.

In contract, UMing HK includes 4940 out of the 4941 glyphs.
