match: write forceincludematcher using unionmatcher

The forceincludematcher is simply a unionmatcher of a includematcher
(matching paths recursively) with the given matcher. Since the
forceincludematcher is only used by sparse, move it there.

I don't have a good sparse repo setup to test performance impact on.
