This leaves only the existence of audioserver 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 audioserver_current
except those created by other domains' allow rules referencing
audioserver domain from public and vendor policies.
