perf diff: Refactor diff displacement possition info

Browse Source 
Moving the position calculation into the diff command, so the position
as prepared inside struct hist_entry data and there's no need to compute
in the output display path.

Removing 'displacement' from struct perf_hpp as it is no longer needed.
