t5616: test cloning/fetching with sparse:oid=<oid> filter

Browse Source 
We test in t5317 that "sparse:oid" filters work with rev-list, but
there's no coverage at all confirming that they work with a fetch or
clone (and in fact, there are several bugs). Let's do a basic test that
a clone fetches the correct objects.

[jk: extracted from Jon's earlier fix patches. I also simplified the
     setup down to a single sparse file, and I added checks that we got the
     right blobs]
