Code review comment for ~gary-wzl77/ubuntu-app-platform:cjk_font

Thanks for the MR.

When I look at http://packages.ubuntu.com/search?keywords=ttf-wqy-microhei it seems that this was the package name in precise, and in newer releases the description says it is a dummy package. I think it is better to use the name of the new package directly.

Also there is a typo (copied from the precise package name), the 'f' missing at the end of sans-serif.
