rtla/tests: Test timerlat -P option using actions
The -P option is used to set priority of osnoise and timerlat threads.
Extend the test for -P with --on-threshold calling a script that looks
for running timerlat threads and checks if their priority is set
correctly.
As --on-threshold is only supported by timerlat at the moment, this is
only implemented there so far.
