System UID apps want to be able to create/write to system-owned /data directories outside of their own /data/data package directory, such as /data/system/cache and /data/misc/keychain. Restore access (which was removed by Ifa10e3283b07f6bd6ecc16eceeb663edfd756cea when system_app_data_file was introduced for the /data/data package directories of system UID apps), but audit writes to system_data_file so we can look at introducing separate types for these directories in the future and ultimately remove access to the rest of the system-owned data.
