    Use the caps that the pad is asked to accept as filter for the query

    basetransform: optimize default acceptcaps implementation

    Pass the fixed caps we're asked to accept as a filter for the caps
    query, so we don't get a fully-expanded set of caps back (which we don't
    need and can take a lot of time for intersection).

    This reduces the time for camerabin to produce a second frame on a
    logitech C910 camera from around 52 seconds to a bit less then 16
    seconds on my system.
