Modifies the given @caps into a representation with only fixed
values. First the caps will be truncated and then the first structure will be
fixated with gst_structure_fixate().
This function takes ownership of @caps and will call gst_caps_make_writable()
on it so you must not use @caps afterwards unless you keep an additional
reference to it with gst_caps_ref().
