[PATCH] get_maintainer.pl: optionally ignore non-maintainer tags

[florian]

Using --git to determine who to send a patch to, it is not
reasonable to include people that only reported an issue or tested a
patch. Thus we restrict the candidates to be the one's listed with
Reviewed-By, Signed-Off-By and Acked-By tags.

Signed-Off-By:'s because that are people who are responsible for the code
in question.

Reviewed-By:'s because people responsible for the code in question
obviously thought that the review-feedback for this changeset by that
person was valuable.

The Acked-By: is questionable, but as people listed with this tag
tend to be active linux gatekeepers, false positives are tolerable.
