Itamar bb1ad759c5 Kernel: Allow calling sys$waitid on traced, non-child processes ...

Previously, attempting to call sys$waitid on non-child processes
returned ECHILD.

That prevented debugging non-child processes by attaching to them during
runtime (as opposed to forking and debugging the child, which is what
was previously supported).

We now allow calling sys$waitid on a any process that is being traced
by us, even if it's not our child.
