            kernel/selinux-testsuite: exclude userfaultfd on old kernels

On RHEL-7 (and other old kernels), __NR_userfaultfd may not be defined
on some arches, so add a kernel version check for now to exclude
userfaultfd test when it would be skipped anyway.

I'll fix this more nicely in upstream, this is just a temporary solution
until that gets merged.
