Ensure that only desired processes can access TracingServiceProxy
This change adds a neverallow rule in traced.te to limit the processes
that can find tracingproxy_service, the context for TracingServiceProxy.
I wanted to avoid moving the tracingproxy_service definition to public,
so there were a few services that are exempted from this neverallow
rule.
Bug: 191391382
Test: Manually verified that with this change, along with the other
change in this topic, I see no errors when taking a bugreport while a
Traceur trace is running and the expected trace is included in the
generated bugreport.
