Use KVM_SET_USER_MEMORY_REGION2 throughout KVM's selftests library so that
support for guest private memory can be added without needing an entirely
separate set of helpers.

Note, this obviously makes selftests backwards-incompatible with older KVM
versions from this point forward.

Is there a way we could disable the tests on older kernels instead of
making them fail?  Check uname or something?  There is probably a
standard way to do this...  It's these tests which fail.

They shouldn't fail - the tests should be skipped on older kernels.
If it is absolutely necessary to dd uname to check kernel version,
refer to zram/ for an example.
