The header uses `NULL` in both `CONFIG_KUNIT=y` and `=n` cases, but does not include it explicitly. When `CONFIG_KUNIT=y`, the header is already getting included via the other headers, so it is not a problem for users. However, when `CONFIG_KUNIT=n`, it is not, and thus a user could hit a build error when including `kunit/test-bug.h`, like we are doing later in this series [1]. Thus include `linux/stddef.h`, and do so outside the `#if`, since it is used in both cases.
