[LTP] [PATCH] syscalls/madvise06: Exclude other factor that leading to failure

[Xiao Yang]

Make sure that madvise(MADV_WILLNEED) supports swap prefetch. We
can't distinguish between kernel bug and unsupported swap, because
the same error happens on RHEL6.8GA which madvise(MADV_WILLNEED)
doesn't support swap prefetch. This feature has been pushed since
kernel 3.10.0.
