The good news is that the deltarpms we generate aren't rpm-only, and
regular deltarpms start with a copy of the rpm's header (which *does*
have the hash format).

We just have to decide whether the checksums deltarpm generates for rpms
with sha256 checksums will be sha256 or md5.  (And I think we should
probably go with sha256, to be consistent.)

I'm going to wait for Michael's response as he's upstream.  I will try
modifying deltarpm to only generate sha256 checksums when the rpm
contains them, but it looks like it's going to be invasive, and Michael
knows the code much better than I do.
