Add LOCAL_JNI_SHARED_LIBRARIES_ABI build variable.
LOCAL_JNI_SHARED_LIBRARIES_ABI allows individual APKs to specify
specify the path where JNI shared libraries are stored in the APK. This
is useful if you want to build an APK that supports a generic version of
an ABI (e.g. armeabi) from a device configuration where
TARGET_CPU_ABI is set to a more specific version of an ABI (e.g.
armeabi-v7a.)
Note that specifying the LOCAL_JNI_SHARED_LIBRARIES_ABI does not
affect how the local JNI shared libraries are built. It just controls
where the local JNI shared libraries are placed within the APK.
Defaults to TARGET_CPU_ABI.
