tracing/probe: Show subsystem name in messages

mhiramat · rostedt · commit 7257634135c2 · 2017-02-15T09:02:25.000-05:00
Show "trace_probe:", "trace_kprobe:" and "trace_uprobe:" headers for each warning/error/info message. This will help people to notice that kprobe/uprobe events caused those messages.
