[LTP] [PATCH 1/3] sched_xxx: TCONF instead of TFAIL if user is not root

[Dejan Jovicevic]

Tests sched_rr_get_interval01, sched_rr_get_interval02,
sched_rr_get_interval03, sched_setparam02 and sched_setparam03
break with TFAIL if they are not ran as root. This is because
they all require setting scheduling policy to SCHED_RR or other
requiring super user privileges.
This was changed so that tests break with TCONF reporting the
appropriate message to the user if he is not root.
