Switch to a class require for deployment

Currently the second requirement for the ROOT.war deployment is an
Exec requirement that comes deep from within biemond-wildfly. This
is a layering violation and makes it impossible to upgrade the module.
Require the install class itself, rather than a part of its internals.
