[PATCH v2 08/10] test: add test for --use-mailmap option

[Junio C Hamano <gitster@pobox.com>]

From: Antoine Pelisse <apelisse@gmail.com>

The new option '--use-mailmap' can be used to make sure that mailmap
file is used to convert name when running log commands.

The test is simple and checks that the Author line
is correctly replaced when running log.
