[ndctl v3 PATCH 7/9] test/libndctl: Enable libndctl tests on ndtest

[Shivaprasad G Bhat <sbhat@linux.ibm.com>]

The ndtest/papr dsm don't have the smart threshold payloads defined
and various smart fields like media/ctrl temperatures, spares etc.

Test only whats relevant and disable/skip the rest.
