Allow src and dst to be identical in pixman_f_transform_invert()

It is useful to be able to invert a matrix in place, but currently
pixman_f_transform_invert() will produce wrong results if you pass the
same matrix as both source and destination.

Fix that by inverting into a temporary matrix and then copying that to
the destination.
