Support usage of boot/addons via symlink to corresponding git repository

It's annoying when you are running grml-live from the git repository,
as the installed grml-live-addons package doesn't matter then,
because the templates are pointing to the git repository.
This can be handled via a symlink, support its usage and mention
it in the docs.
