We didn't release the get/setPackageObbPath API, but it snuck into
MockPackageManager. However, it is not usable as a developer anyway.
Removing it so it doesn't stay in the API forever.
Cherry-pick from gingerbread

9.xml -- the GB 2.3 API being released.
10.xml -- a place holder for the GB 2.4 API that is in progress.
11.xml -- the HC API that is in progress.
Currently 10.xml is just a copy of 9.xml, but it will get updated
as changes are made to GB.
Note there is a big unfortunate result here, that any new GB APIs
that are added need to be hand-merged to 10.xml. Joy.
