[PATCH] Update git-tag-script to create the .git/refs/tags if it does not already exist

When testing tags I ran into an interesting problem.
git-tag-script dies if .git/refs/tags/ does not exist.
And that directory didn't get created when I build my repository,
so we need to create it if it doesn't exist.
