Update templates to remove deprecation warnings

Signed-off-by: Konrad Scherer <Konrad.Scherer@windriver.com>
Remove deprecated concat::setup

This is deprecated in concat 1.1.0 and the Modulefile already
lists this version of concat as a dependency

Note: the README for concat says concat::setup was deprecated in
1.0.0 but the changelog lists 1.1.0.
