Create a new label for /data/system/dropbox, and neverallow direct
access to anything other than init and system_server.

While all apps may write to the dropbox service, only apps with
android.permission.READ_LOGS, a signature|privileged|development
permission, may read them. Grant access to priv_app, system_app,
and platform_app, and neverallow access to all untrusted_apps.

This is a partial cherry pick of commit 6231b4d9
'Enforce per-app data protections for targetSdk 28+'.

Untrusted_app_27 remains unreachable, but it's existence
prevents future merge conflicts.

Restrictions introduced in vendor init mean that new devices
may not no longer exempt vendor init from writing to system_data_file.
This means we must introduce a new label for /data/vendor which
vendor_init may write to.
