Add additional parameters to `doRestoreFile` to IBackupAgent.aidl

The cross-platform API change has made it possible to pass additional
parameters to the BackupAgent's onRestoreFile method, such as the app
version code and transport flags. This change updates the aidl
definition to allow e.g. the restore engine to pass these extra
parameters to the BackupAgent.
