Allow traced to notify traceur via property
This CL introduces allows traced to set the
sys.traceur.trace_end_signal property at the end
of the tracer. In turn that property notifies the
the Traceur app.
This is to allowing Traceur to be killed during
a long-trace and avoid wasting resources making
it a persistent service.
See aosp/886616 for the matching traceur change.
