Just symlink all hooks found in the gitlab-shell project

Make it possible to place whatever hooks you want inside the hook
folder of the gitlab-shell and they will be symlinked as well. The
symlinks are created when:

* running the support/rewrite-hooks.sh
* Creating a new repo in gitlab

So basically it makes the hooks folder a skeleton for all other projects
