modules: add missing libraries and plugins to Corrade dependency lookup.

Looks like until now all find_package() calls included the other
transitive dependencies as well, so this accidentally worked. But for
example with the DebugTools reliance on SceneGraph and Primitives now
being deprecated, this may change.
