[PATCH 10/22] mailmap tests: get rid of overly complex blame fuzzing

Change a test that used a custom fuzzing function since bfdfa3d414 (t4203 (mailmap): stop hardcoding commit ids and dates, 2010-10-15) to just use the "blame --porcelain" output instead.

We could use the same pattern as 0ba9c9a0fb (t8008: rely on rev-parse'd HEAD instead of sha1 value, 2017-07-26) does to do this, but there wouldn't be any point. We're not trying to test "blame" output here in general, just that "blame" pays attention to the mailmap.

So it's sufficient to get the blamed line(s) and authors from the output, which is much easier with the "--porcelain" option.

It would still be possible for there to be a bug in "blame" such that it uses the mailmap for its "--porcelain" output, but not the regular output. Let's test for that simply by checking if specifying the mailmap changes the output.
