Remove auditallow from system_server.

system_server auditallow statements were causing logspam and
there is not a good way to negate services from specific devices
so as a fix we are removing all system_server auditallows. These
logs may not be useful anyway because I suspsect that system_server
will probe for most all services anyway.
