x86: traps_xx: modify x86_64 to use _log_lvl variants
i386 has show_trace_log_lvl and show_stack_log_lvl, allowing traces to be emitted with log-level annotations. This patch introduces them to x86_64, but log_lvl is only ever set to an empty string. Output of traces is unchanged. i386-chunk is whitespace-only.
