Some ndctl tests use two new mmap() flags named MAP_SHARED_VALIDATE
and MAP_SYNC that were added by linux kernel-4.15, intended to be
defined for applications by sys/mman.h. However, these do not exist
unless the distro has glibc-2.28.
In addition to the existing check for MAP_SYNC, check that
MAP_SHARED_VALIDATE is provided.
Fixes: 94679e6b78aa ("ndctl, test: check availability of MAP_SYNC for poison
test")
