[PATCH 3/4] Teach git-submodule.sh about the .git file

[Lars Hjemli <hjemli@gmail.com>]

When git-submodule tries to detect 'active' submodules, it checks for the
existence of a directory named '.git'. This isn't good enough now that .git
can be a file pointing to the real $GIT_DIR so the tests are changed to
reflect this.
