Fix matrix bindings for distributed matrices

[ckendrick]

This fixes some overloads for the Matrix class when used with distributed matrices or vectors.

For example, the following example would fail when A and C are pre-defined and distributed:

import numpy as np
import pylibROM.linalg as linalg

A = linalg.Matrix(5, 3, True)
A[0,0] = 1.; A[1,1] = 1.; A[2,2] = 1.
B = linalg.Matrix(3, 5, False)
B[0,0] = 1.; B[1,1] = 1.; B[2,2] = 1.
C = linalg.Matrix(3,3,True)
C = A.mult(B)

However, the A.mult(B, C) variation of this worked as expected. Bindings for other Matrix functions using similar syntax to C = A.mult(B) with distributed inputs are now fixed.
