Add .repo and internal project/* folders to .gitignore
Internal projects are checked out using a `repo` manifest as subfolders
in project/. Git treats these as untracked files and `git status`
reports the repository dirty. Add .repo/ and project/* (other than
project/reference) to .gitignore to work around the issue.
