system_file_type is a new attribute used to identify files which exist
on the /system partition. It's useful for allow rules in init, which are
based off of a blacklist of writable files. Additionally, it's useful
for constructing neverallow rules to prevent regressions.
Additionally, add commented out tests which enforce that all files on
the /system partition have the system_file_type attribute. These tests
will be uncommented in a future change after all the device-specific
policies are cleaned up.
Test: Device boots and no obvious problems.

This change makes it such that only init can start adbd directly. It
also introduces new rules for ctl.{start,stop,restart} properties such
that only usbd and recovery (and su, since it's permissive) can directly
ask init to start adbd.
