[PATCH] bug: fix warning suppressions with kunit built as module

[Bartosz Golaszewski]

CONFIG_KUNIT is a tristate symbol but the warning suppression code in
lib/bug.c is only built if it's built-in. Use IS_ENABLE(CONFIG_KUNIT) to
enable it for a loadable kunit module as well. When using a plain #ifdef,
the suppressions only work if kunit is built-in.
