[LTP] [PATCH] madvise11: Allow test to skip if MADV_SOFT_OFFLINE is not supported

Hi!

Does it make sense to keep the test running if the config option is not
present? As far as I can tell we are trying to reproduce a race there
that depends on the madvise being able to soft offline the pages.

What about this then?
