t9351: derive anonymized tree checks from original repo

Our tests of the anonymized repo just hard-code the expected set of
objects in the root and subdirectory trees. This makes them brittle to
the test setup changing (e.g., adding new paths that need tested).

Let's look at the original repo to compute our expected set of objects.
Note that this isn't completely perfect (e.g., we still rely on there
being only one tree in the root), but it does simplify later patches.
