tracing: Convert some signal events to DEFINE_TRACE
Use DECLARE_EVENT_CLASS to remove duplicate code:
text data bss dec hex filename
23639 6084 8 29731 7423 kernel/signal.o.orig
22727 6084 8 28819 7093 kernel/signal.o
2 events are converted:
signal_queue_overflow: signal_overflow_fail, signal_lose_info
No functional change.
