contrib: add a basic gitdm config

This is a QEMU specific version of a gitdm config for generating
reports on the contributor base of the project. I've added enough
group maps and domain aliases to ensure the current top ten is as
reflective as it can be. As of this commit running:

  git log --numstat --since "Last Year" | gitdm -n -l 10
