I guess this itself fix many false positives :). I'm ok with requesting RT
kernel, but just to remind the claim originated from Cyril [1] "sched_football
is useful not only for testing realtime". So was Cyril wrong?

(I'm ok to keep the test in runtest/sched even requesting RT kernel, because
runtest/sched and other LTP tests are run on both RT and non-RT.

The rest LGTM, thanks for stabilising the test.
