[PATCH 2/2] trace-cmd: make libtracecmd a little more library friendly

[Josef Bacik]

You get a lot of debug output if you link directly against libtracecmd if you
don't provide your own pr_stat() function because we default to something that
actually prints stuff out.  Fix this by making pr_stat() do nothing by default.
This also changes the printf() for the version number to a pr_stat().  Thanks,
