libmalcontent: Factor getting/setting app filter into a manager

Create a new MctManager object which is used as the anchor for getting
or setting MctAppFilters.

This changes the API naming around quite a bit, but doesn’t really
change its behaviour or functionality — see the tests for examples of
how little things change.

This is one step on the way to emitting a signal (from MctManager) when
a user’s parental controls change.
