mesa/sso: Implement _mesa_GetProgramPipelineiv

Browse source 
This was originally included in another patch, but it was split out by
Ian Romanick.

v2 (idr):
* Trivial reformatting.
* Remove GL_COMPUTE_SHADER.  Compute shaders don't participate in pipeline
  objects anyway.  Suggested by Matt Turner.

v3 (idr):
* Use _mesa_has_geometry_shaders.
