s390/bug: Add missing CONFIG_BUG ifdef again

Fallback to generic BUG implementation in case CONFIG_BUG is disabled.
This restores the old behaviour before 'cond_str' support was added.

It probably doesn't matter, since nobody should disable CONFIG_BUG, but at
least this is consistent to before.

Fixes: 6584ff203aec ("bugs/s390: Use 'cond_str' in __EMIT_BUG()")
