profiling: show actual time spent in hotpath display

To get, for instance:

   |  6.5%  4.01s  exchange.py:    close           line 1191: ...

   |  6.2%  3.81s  localrepo.py:   updatecaches    line 177:  ...
   ...

instead of:

...
 \  6.6%  lock.py:        __exit__          line 1566: ...
   |  6.5%  exchange.py:    close           line 1191: ...
   |  6.5%  transaction.py: _active         line 1443: ...
   |  6.5%  transaction.py: close           line 47:   ...

   |  6.2%  localrepo.py:   updatecaches    line 177:  ...
   ...

I find that if it's not displayed, I frequently end up estimating the
numbers by hand.
