Split up the corrupt_graph_and_verify() function added in d9b9f8a6fd ("commit-graph: verify catches corrupt signature", 2018-06-27) into its logical components of setting up the test itself, doing the corruption in a particular way with "dd", and then finally testing that stderr is what we expect.
This allows for re-using everything except the now slimmer corrupt_graph_and_verify() to corrupt the graph in a way that doesn't involve inserting a given byte sequence at a given position, e.g. truncating it entirely to a custom value.
