bug: fix warning suppressions with kunit built as module

CONFIG_KUNIT is a tristate symbol but the warning suppression code in
lib/bug.c is only built if it's built-in due to it using a plain #ifdef,
rendering warning suppressions broken for kunit build as loadable module.

kunit_is_suppressed_warning() already has a stub for when kunit is
disabled so drop that guard entirely.
