[PATCH] devtools: fix name check with mbox files

[David Marchand]

When passing a patch downloaded as mbox, the mail headers were being
scanned which resulted in mailing list and other unrelated mail
addresses being checked against the contributors list.

Filter them by focusing on the mail body (separated from the headers
with the first empty line).

Fixes: e83d41f0694d ("mailmap: add list of contributors")
