bugfix: don't let children stay Litmus real-time tasks

It has always been LITMUS^RT policy that children of real-time tasks
may not skip the admissions test, etc. This used to be enforced, but
was apparently dropped during some port. This commit re-introduces
this policy.  This fixes a kernel panic that occurred when "real-time
children" exited without proper initilization.
