Don't use the shader key when forcing it.
Changing a shader key within vrend_create_shader will always force
virglrenderer to recreate the shader the next time it is looked up, so
memory usage will grow and performance will go down.
Also it is actually not needed if with each emitted back color also has a
corresponding front color is emitted. So restrict forcing two-sided coloring
to the cases where a back color is emitted without a front color, and don't
change the shader key.
