[PATCH] Fix git-init-db creating crap directories.

[PATCH] Fix git-init-db creating crap directories.

The base target directory for the templates copying was initialized
to git_dir, but git_dir[len] is not zero but / at the time we do the
initialization. This is not what we want for our target directory string
since we pass it to mkdir(), so make it zero-terminated manually.
