`strerror_s` is the windows alternative of `strerror_r` used by EFL.
`strerror_s` never return the error code with the message as
`strerror_r` does, because of that, while comparing the first 14
characters of `Unknown error ` to the message from unknown code 4096
(`Unknown error`) they were accusing being different - in UNIX this
works because the message returned is `Unknown error 4096`.
This error was noticeable at `eina_error_test_failures` test case.
This Diff adds the error code to the message in case of an `Unknown
error`, making the windows implementation compliant with UNIX.
