[Piglit] [PATCH] tests/spec: added minmax tests for arb_shader_storage_buffer_object

[Aditya Atluri]

---
v2: - changed gl_core to 40, removed whitespace, 
      changed min test to max test for offset of alignment,
      changed block size to 2^27 (Ilia)
v3: - removed link library glu,
      removed include libraries in tests/util,
      changed block size back to 2^27,
      added run_concurrent=True in all.py
