igt/drv_missed_irq: Sleep in the child waiting for the parent
Our parent is RT, we are not. In theory, we should wait until our parent
has gone to sleep before we are allowed to proceed (we should both be
bound to the same cpu). Double down on this by sleeping in the child
until our parent has written a byte along a pipe().
