Applied to kvm-x86 selftests_utils (I had already pushed stuff to "selftests",
so the name is less than awesome).

Other KVM maintainers, I also created tags/kvm-x86-selftests-utils if you want
to pull this into your tree to avoid later merge conflicts with the
kvm_util_base.h => kvm_util.h rename.  I don't expect to push anything else to
the branch, but never say never. 

Note, this branch+tag also has the _GNU_SOURCE change, and the global pseudo-RNG
series ("thank yous" incoming), i.e. it's hopefuly a one stop shop for all your
6.10 selftests needs!
