examples: Fix the first colour in the triangle_vertices

Browse Source 
The first vertex in the triangle vertices used in the cogl-hello
example (which were copied into a few other examples) for some reason
has a semi-transparent alpha component. However the colour needs to be
pre-multiplied and the red component was still 0xff so the colour is
effectively invalid and the transparency isn't shown. This patch just
sets the alpha component to 0xff to make it less confusing.
