`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We should prefer more robust and less ambiguous string interfaces. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer. With this, we can also drop the now unnecessary `CPUIDLE_(NAME|DESC)_LEN - 1` pieces.
