From: Han-Wen Nienhuys <hanwen@google.com>

We have some tests that read from files in .git/logs/ hierarchy when checking if correct reflog entries are created, but that is too specific to the files backend. Other backends like reftable may not store its reflog entries in such a "one line per entry" format.

Update for-each-reflog-ent test helper to produce output that is identical to lines in a reflog file files backend uses. That way, (1) the current tests can be updated to use the test helper to read the reflog entries instead of (parts of) reflog files, and perform the same inspection for correctness, and (2) when the ref backend is swapped to another backend, the updated test can be used as-is to check the correctness.

Adapt t1400 to use the for-each-reflog-ent test helper.
