Normalize nan/-nan in plugin/msgpack_spec.lua

Browse Source 
-NaN doesn't exist in the IEEE 754 spec, it is a hardware-specific detail
abstracted away by luajit(and not by lua or nvim), so there's no need to test
it.  Normalize all tests that involve -nan so the suite will be compatible with
both Lua and Luajit.
