[PATCH v4 2/2] t4041: test SHA-256 submodule abbreviations

["Srujith A Poojary via GitGitGadget" <gitgitgadget@gmail.com>]

From: Srujith A Poojary <poojarysrujith@gmail.com>

The expected abbreviation for a submodule commit depends on the
repository's hash algorithm. Use test_oid_cache to provide the
expected value for each algorithm and remove the SHA1 prerequisite
so this test runs with both SHA-1 and SHA-256.
