Arrange pack files in recency order to improve quick hits
Packs with newer modification dates are more likely to contain data
related to recent commits, and thus will have a better probability
of containing an object we care about when we are looking only at
recent history.
In some cases, this may permit JGit to avoid reading a very large
historical pack's index file into memory if the only data we ever
need is available in newer pack files.
