[LTP] [PATCH] waitpid06: use the new API

I've even tried to subscribe to the uClinux-dev mailing list but it
looks like nobody manages it anymore. So I guess that we may start
dropping support for it.

Hmm, I guess that there is no reason for this indirection anymore. We
can just start MAXKIDS processes directly from the test() function.

Otherwise it looks good.
