swrast: Only avoid empty _TexEnvPrograms
If the generated shader for _TexEnvProgram is empty, force the use of
the fixed-function code. Otherwise, go ahead and use the shader.
This works around a mysterious issue on i915 where fixed-function
software fallbacks are not working correctly.
This isn't really the fix we want, but it works around the issue.
