[PATCH V2] get_maintainer: Add email addresses from .yaml files

[Joe Perches <joe@xxxxxxxxxxx>]

.yaml files can contain maintainer/author addresses and it seems
unlikely or unnecessary that individual MAINTAINER file section
entries for each .yaml file will be created.

So add the email addresses found in .yaml files to the default
get_maintainer output.

The email addresses are marked with "(in file)" when using the
"--roles" or "--rolestats" options.

Miscellanea:

o Change $file_emails to $email_file_emails to avoid visual
  naming conflicts with @file_emails

V2: Fix dd/add typo
    Add Sam's sign-offs
    Resend using git format-patch git send-email and UTF-8 not 8-bit
