lib/cobalt: Forward kill to Linux if no target was found
If the user targets a task that is not under Xenomai control, retry the
call via Linux as it may be a regular task.
As this changes the semantics also for internal users, adjust
copperplate_probe_tid to use the new RT-safe cobalt_thread_probe
service instead.
