DEBUG: cli: relax tid check in "debug dev task" for recent sched changes

Since commit 0988b9c773 ("MEDIUM: tasks: Remove the per-thread group
wait queue") in 3.5-dev, a task's tid may be as negative as -MAX_THREAD-1
and not just -1, so we must accept this when trying to check if a pointer
looks like a valid task.

No backport is needed.
