[PATCH v2 1/4] t6006: simplify and optimize empty message test

From

Test t6006.71 ("oneline with empty message") was creating two commits with simple commit messages, and then running filter-branch to rewrite the commit messages to be empty. This test was written this way because the --allow-empty-message option to git commit did not exist at the time. Simplify this test and avoid the need to invoke filter-branch by just using --allow-empty-message when creating the commit.

Despite only being one piece of the 71st test and there being 73 tests overall, this small change to just this one test speeds up the overall execution time of t6006 (as measured by the best of 3 runs of `time ./t6006-rev-list-format.sh`) by about 11% on Linux and by 13% on Mac.
