perf report: Change default callchain parameters
The default callchain parameters are set to use the flat mode and never filter any overhead threshold of backtrace. But flat mode is boring compared to graph mode. Also the number of callchains may be very high if none is filtered. Let's change this to set the graph view and a minimum overhead of 0.5% as default parameters.
