Dear Fonts Team, Chinese developers and czchen,

As previously discussed on the Chinese list, we want to make Noto CJK fonts 
the "default" one on all Chinese environments, or at least on those Chinese 
locales that are supported by Noto CJK fonts [1].As a result, I'm proposing to 
tweak its fontconfig config files to achieve that.

This would also workaround some weird results on fontconfig's font selecting, 
e.g., on installing fonts-arphic-gkai00mp (which is rather legacy these days), 
fontconfig on zh_CN systems would receive a (weirdly) high priority for all 
sans, sans-serif, serif and monospace fonts.
