t4044: update test to work with SHA-256
This test produces pseudo-collisions and tests git diff's behavior with
them, and is therefore sensitive to the hash in use. Update the test to
compute the collisions for both SHA-1 and SHA-256 using appropriate
constants. Move the heredocs inside the setup block so that all of the
setup code can be tested for failure.
