This improves caps negotiation to avoid returning caps that it will not
support.

The issue arrises when a caps has a certain capsfeatures X and the cached
converter_caps has ANY caps features. When the intersection of the cached caps
with the filter happens it transforms the ANY into X and those features are not
excluded in the loop. If the sink doesn't accept those features it would cause
a not-negotiated issue later when the caps event is passed.
