Add prebuilt of android_system.jar as of build LRW76 #1434926

We added prebuilt SDK version "system_current".
The android.jar was grabbed from the SDK build target's
android_system.jar on the build page.
Since we don't have system API of aidl, we don't need new
framework.aidl. We just symlink system_current/framework.aidl to
current/framework.aidl.

With this change, you can build an app against the current version of
system APIs in unbundled (tapas) build with:
LOCAL_SDK_VERSION := system_current

Later when API level 21 is settled down, we will add numberic system
API levels such as system_21, so you can reference them with
"LOCAL_SDK_VERSION := system_<number>".
