Fix LibInfo unmarshalling exception in Linker

Fix LibInfo unmarshalling exception in Linker

This patch fixes the Chromium Android Linker bug which causes a
RuntimeException when LibInfos are unmarshalled from the shared RELRO
Bundle in renderer process. The problem was caused by an ABI mismatch
between ParcelFileDescriptor.writeToParcel() and
Parcel.readFileDescriptor() (b/19451018).
