With the preceding commit in mind that introduced GIT_HASH_ORIGINAL you
could also argue that those callsites should be converted to use that
define instead. We always used to treat them as SHA1 repositories, and
we have no better way of telling otherwise, so we use the historical
value of SHA1 so that scripts aren't dependent on how exactly Git was
built.
