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: 043ca389 ("perf tools: Use hpp formats to sort final output")
