Christian Couder 66589f89ab t/helper: add 'find-pack' test-tool
In a following commit, we will make it possible to separate objects in
different packfiles depending on a filter.

To make sure that the right objects are in the right packs, let's add a
new test-tool that can display which packfile(s) a given object is in.

Let's also make it possible to check if a given object is in the
expected number of packfiles with a `--check-count <n>` option.
