perf tools: Fix time sorting
The final sort might get confused when the comparison is done over
bigger numbers than int like for -s time.
Check the following report for longer workloads:
$ perf report -s time -F time,overhead --stdio
Fix hist_entry__sort() to properly return int64_t and not possible cut
int.
Fixes: 043ca389a318 ("perf tools: Use hpp formats to sort final output")
