[HarfBuzz] Thai text render issue in Android L

[Roozbeh Pournader]

With the latest HarfBuzz and Noto Sans Thai, I'm seeing the result I'm
attaching, which appears correct to me (and the same as Android Kitkat
result you've attached).

But I see the same as what you are seeing on Android Lollipop. So this
appears to be a bug somewhere in Android rather than HarfBuzz or Noto Sans.

Please file a bug at https://source.android.com/source/report-bugs.html and
send us a link to it. Thanks.
