clover: Add a stub implementation of clCreateImage() v3

Now that we are uisng the OpenCL 1.2 headers, applications expect all
the OpenCL 1.2 functions to be implemented.

This fixes linking errors with the piglit CL tests.

v2:
  - Use c++ features
  - Fix error code handling

v3:
  - Move <iostream> into api/util.hpp
  - Fix indentation
