tools/testing/nvdimm: make iset cookie predictable
For testing changes to the iset cookie algorithm we need a value that is
constant from run-to-run.
Stop including dynamic data in the emulated region_offset values. Also,
pick values that sort in a different order depending on whether the
comparison is a memcmp() of two 8-byte arrays or subtraction of two
64-bit values.
