patman: Add a call to get_maintainer.pl if it exists
For Linux the best way to figure out where to send a patch is with the
"get_maintainer.pl" script. Add support for calling it from patman.
Support is added unconditionally for "scripts/get_maintainer.pl" in
case it is helpful for any other projects.

During the first run patman creates a config file for you by taking the default
user name and email address from the global .gitconfig file.
