Export SDK library names
A java module exports SDK library names that it is using directly or
indirectly via its dependencies. Manifest fixer uses the SDK lib names
to automatically add <uses-library> tags for the apk.
The SDK library names are exported via exported-sdk-libs file in make.
From Soong, they are exported via LOCAL_EXPORT_SDK_LIBRARIES flag.
