Add /data/storage_area to app data directories
libselinux has special handling for the app data directories such as
/data/user/$userId/$pkgName and /data/user_de/$userId/$pkgName, because
their SELinux contexts are determined differently from "normal" files.
/data/storage_area/$userId/$pkgName will be a new app data directory
(with a different SELinux context, but determined through the same process).
THerefore, add it to the list of app data directories.
