t5538: add tests to confirm deltas in shallow pushes
It can be notoriously difficult to detect if delta bases are being
computed properly during 'git push'. Construct an example where it will
make a kilobyte worth of difference when a delta base is not found. We
can then use the progress indicators to distinguish between bytes and
KiB depending on whether the delta base is found and used.
