[Piglit] [PATCH] CL: Add basic mapped memory tests

[Aaron Watry]

Tests blocking map for read/write by:
- Creating host/device src/dst buffers
- Map device src buffer for writing, and memcpy to it before unmapping
- enqueueCopyBuffer from src to dst
- Map device dst buffer for read, and memcpy from it before unmapping
- Compare host src/dst buffers for equality
