[Piglit] [PATCH v3] sso: test program pipeline with atomic counters

Test fails on current Mesa and NVIDIA binary driver version 355.11 and
passes on AMD binary driver version 15.201.1151.

v2: - add error checks
    - modify to render points
    - make it possible to use regular program (makes test pass on Mesa)

v3: - bump up glsl version to 1.50 and redeclare gl_Position in vs
      (makes the vs compile and test pass on AMD)
