diff_stats: use git's formatting of renames with common directories
In cases where a file gets renamed such that the directories containing
it previous and after the rename have a common prefix, then git will
avoid printing this prefix twice and instead format the rename as
"prefix/{old => new}". We currently didn't do anything like that, but
simply printed "prefix/old -> prefix/new".
Adjust our behaviour to instead match upstream. Adjust the test for this
behaviour to expect the new format.
