Move system_server policy to private
This leaves only the existence of system_server domain as public API.
All other rules are implementation details of this domain's policy
and are thus now private.
Test: No change to policy according to sesearch, except for
disappearance of all allow rules to do with
system_server_current except those created by other domains'
allow rules referencing system_server domain from public and
vendor policies.
