Ignore .repo directories created by the git-repo tool

git-repo [1] is used to manage multiple Git repositories. The .repo
directory contains the consolidated Git histories of the managed 
projects (which are symlinked from the individual projects' .git 
repositories), so we should ignore the .repo directory just like the 
.git directory.

However, the .repo directory also contains the source code to the 
git-repo tool itself. One might argue that this source code should be 
picked up during a scan, but then again the code of git-repo is not 
integrated into the deliverable / what is being built from the source 
code as git-repo is just a VCS tool, so a user is probably not 
interested in any license findings in git-repo.
