[PATCH 1/3] dim: redo the author sob checks

[Daniel Vetter]

This reverts commit 41dddc0287bb9ef14be8de3c3185ed6aaa809d98 and then
tries a different approach because from the commit that originally
introduced this:

commit 3dd25f235c73f7855dc570585eb2551961a1911a
Author: Benjamin Gaignard <benjamin.gaignard at linaro.org>
Date:   Wed Jul 26 14:07:49 2017 +0200

    dim: add checks for author and committer sign-off-by

we have

    "Use real names for people with many different email addresses."

to work around outlook we need to convert the "Last, First" firm into
what git expects instead, which also should solve the problem Rodrigo
has.
