* Noto: remove the UI variants. According to the FAQ [1]:
"The UI fonts were initially prepared for use in Android’s UI. They
have tighter vertical metrics, and some glyphs that would be clipped
are redrawn to fit within the constrained space."
As they look pretty much identical to the non-UI versions, we'll
keep them out of the package for the time being. If we see any clipping
they could be re-added (or put in their own sub-package).
* Noto CJK: put the Japanese CJK in a correctly named sub-package.
The 'main package' (declared in PROVIDES) is emtpy and shouldn't be
uploaded to a repo. Haikuporter could be changed to not create a
package, if the PROVIDES is empty.
