Limit eden stale version check to only windows platform

Summary:
As per the discussion in this doc - https://docs.google.com/document/d/1fTxlasZfWv58iVhRr6Um3nSIOk4R0e4J6lxsCzG4W9E/edit?usp=sharing
we should limit edenfs stale version check to Windows only, The only cases of an old eden version on non-Windows would be:
1) repeated failed graceful restart (we get alerts for this)
2) no chef run in a while (there is another check for that in this tool)
and both cases are already handled
