perf: Use generic sample reordering in perf trace

Use the new generic sample events reordering from perf trace.
Before that, the displayed traces were ordered as they were
in the input as recorded by perf record (not time ordered).

This makes eventually perf trace displaying the events as beeing
time ordered.
