t5324: harmonize sha1/sha256 graph chain corruption
In t5324.20, we corrupt a hex character 60 bytes into the graph chain
file. Since the file consists of two hash identifiers, one per line, the
corruption differs between sha1 and sha256. In a sha1 repository, the
corruption is on the second line, and in a sha256 repository, it is on
the first.
We should of course detect the problem with either line. But as the next
few patches will show (and fix), that is not the case (in fact, we
currently do not exit non-zero for either line!). And while at the end
of our series we'll catch all errors, our intermediate states will have
differing behavior between the two hashes.
Let's make sure we test corruption of both the first and second lines,
and do so consistently with either hash by choosing offsets which are
always in the first hash (30 bytes) or in the second (70).
