[PATCH v3 07/21] t4013: make test hash independent

This test produces a large number of diff formats and compares the output with test files that have content specific to SHA-1. Since we are more interested in the format of the diffs, and not their specific values, which are tested elsewhere, add a function which uses sed to transform these specific object IDs into generic ones of the right size, which we can then compare.
