[PATCH 2/4] libtraceevent: Have logs only print to stderr on WARNING or higher

[Steven Rostedt <rostedt@xxxxxxxxxxx>]

From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>

The tep logs should only print to stderr for WARNINGS and higher. Info
messages can go to stdout.

Also, only print perror on warnings or higher.
