Add rules for multi-user backup/restore
The backup system service will move its storage location to per-user CE
directories to support multiple users. Add additional iterations on the
existing rules to support the new location.
/data/backup -> /data/system_ce/[user id]/backup
Previously covered by rule backup_data_file
/cache/backup -> /data/system_ce/[user id]/backup_stage
Previously covered by rule cache_backup_file
Also add support for vold to create and perform restorecon on the new
locations.
Example denials and detailed proposal in the doc on the linked bug.
Bug: 121197420
Test: 1) Boot device; check dirs created with correct label; run backup
successfully on system user
2) Create secondary user; check dirs created with correct label; run
backup successfully
