kunit: test-bug.h: include `stddef.h` for `NULL`

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.
