audiomixmatrix: Remove property matrix-value-array

Browse source 
This duplicated property is no longer needed as there is now API to
allow bindings access GST_TYPE_ARRAY (see gst_util_get/set/object_array).
Additionnally, Python has proper overrides which will make this looks
like Python. A 2x2 matrix would be set this way:

  element = matrix = Gst.ValueArray(Gst.ValueArray([1.0, -1.0]),
      Gst.ValueArray([1.0, -1.0))

Notice that you need to "cast" each arrays to Gst.ValueArray, otherwise
there is an ambiguity between Gst.ValueArray and Gst.ValueList list type.
Fortunatly, Gst.ValueArray implements the Sequence interface, so it can
be indexed like normal python matrix.
