Add initial sepolicy for app data snapshots.
Define a rollback_data_file label and apply it to the snapshots
directory. This change contains just enough detail to allow
vold_prepare_subdirs to prepare these directories correctly.
A follow up change will flesh out the access policy on these
directories in more detail.
