[RFC/PATCH 4/4] t4203: consolidate test-repository setup

[Eric Sunshine <sunshine@sunshineco.com>]

The simple two-commit test-repository created by 'setup' is no longer
needed by any of the tests retrofitted to use check-mailmap. Subsequent,
more complex tests of git-shortlog, git-log, and git-blame functionality
expand the repository by adding five commits. Consolidate the creation
of this seven-commit repository into a single repository-setup function.

Signed-off-by: Eric Sunshine <sunshine@sunshineco.com>
---

The code near the top of the file which creates two commits, and the
code later which creates five commits have been consolidated into a
single repository-setup function. The patch is primarily code movement,
but the noisy diff makes it look more busy than it actually is.
