Bug#907999: fonts-noto-cjk: Unable to use system fonts in Firefox after #907048

[Gunnar Hjalmarsson <gunnarhj@ubuntu.com>]

It may be worth to mention a config file we are using in Ubuntu for the 
CJK languages (attached). We ship fonts-noto-cjk by default, and that 
file seems to be sufficient to allow decent rendering in any CJK 
language irrespective of the locale, i.e. for all users.

As a supplement we use language guarded "prepend" for zh-cn and zh-tw to 
avoid confusion in Chinese user sessions.
