[PATCH] trace-cmd: quiet some output when using libtracecmd

[Josef Bacik]

If you link against libtracecmd you get a few extraneous warnings and printf's
that aren't related to your tool.  So by default make the path to the events you
are tracing use pr_stat() so if it's not defined we don't get the output, and
make the weak warning() do nothing by default.  The trace-cmd stuff has this
defined so it'll continue to work normally, it just won't be noisy for consumers
of libtracecmd.  Thanks,
