avoid using gst_caps_get_size() in gst_pad_fixate_caps

Just truncate and then fixate if something is left. Avoids fully evaluating
lazy
caps.

Remaining offender is gst_base_transform_transform_caps(). Need to implement a
lazy caps iterator here too.

One more question - would it be okay to change the semantics of
gst_caps_get_structure() the return NULL for index>length. Its is doing that
right now via:
g_return_val_if_fail (index < caps->structs->len, NULL);
which I'd like to turn into
if (index >= caps->structs->len)
  return NULL;

That'd allow to write:
ix = 0;
while ( s = gst_caps_get_structure(caps, ix)) {
  ...
  ix++;
}
