tracing/osnoise: Do not follow tracing_cpumask
In preparation to support multiple instances, decouple the
osnoise/timelat workload from instance-specific tracing_cpumask.
Different instances can have conflicting cpumasks, making osnoise
workload management needlessly complex. Osnoise already has its
global cpumask.
I also thought about using the first instance mask, but the
"first" instance could be removed before the others.
This also fixes the problem that changing the tracing_mask was not
re-starting the trace.
