[PATCH 2/3] t8003: factor setup out of coalesce test

[Jeff King <peff@peff.net>]

In preparation for adding more tests of blame's coalesce code, let's
split the setup out from the first test, and give each of the commits
a more meaningful name:

  - $orig for the original source that added the lines

  - $split for the version where they are split apart

  - $final for the final version that re-joins them

That's not strictly necessary, but makes the follow-on tests less
brittle than relying on HEAD^, etc, to name the commits.
