libnvdimm: Enable unit test infrastructure compile checks
The infrastructure to mock core libnvdimm routines for unit testing purposes is prone to bitrot relative to refactoring of that core. Arrange for the unit test core to be built when CONFIG_COMPILE_TEST=y. This does not result in a functional unit test environment, it is only a helper for 0day to catch unit test build regressions. Note that there are a few x86isms in the implementation, so this does not bother compile testing this architectures other than 64-bit x86.
