Fixed raymath not applying matrix translations.

Browse Source 
Translation matrices use the w components of the matrix to apply the
transform, and thus only work when the w component is 1. In the
original raymath implementation, the multiplication is done manually
and adds the translation components directly to the result, as if w is
1, but in the Odin binding this is done with a matrix multiplication.
However, the w component is set to 0 instead of 1, resulting in the
translation not being applied.
