[LTP] [PATCH 1/1] tree: Use TST_EXP_FAIL2() for wait{,id}

[Cyril Hrubis]

Hi!
> Both wait() and waitid() returns PID, therefore (similarly as for file
> descriptor) pass condition is >= 0, which is in TST_EXP_FAIL2().

Actually waitid() returns whatever was waited for in the siginfo_t
structure and returns just 0 on success.
