libnvdimm/nfit_test: adding support for unit testing enable LSS status



Adding support code to simulate the enabling of LSS status in support of
the Intel DSM v1.6 Function Index 10: Enable Latch System Shutdown Status.
This is only for testing of libndctl support for LSS enable. The actual
functionality requires a reboot and therefore is not simulated. The enable
value is not recorded in nfit_test since there's no DSM to actually query
the current status of the LSS enable.
