Subject: [PATCH] Fix printing errors from failed binary runs

I had the kublet die on startup and the only error was "0x401da0"  Which
I assume is an address of the err.Error function.  The other way to fix
this, I think, would be to use err.Error(), however that could cause
fmt.Fprintf() problems, debuging on the error message people used.

Now I get a nice clean error I can understand:

"cAdvisor.New() err = mountpoint for cpu not found"
