Log:
  graphics/darktable: Include `stddef.h` when testing zError() symbol
  
  The `CheckZlib.cmake` module uses `NULL` in the test source code to
  check for the `zError()` symbol. This fails to build on FreeBSD 10.3
  with the following error:
  
      CheckPrototypeDefinition.c:15:10: error: use of undeclared identifier 'NULL'
        return NULL;
               ^
  
  I don't know the root cause for this failure, but including `stddef.h`
  in this test source code fixes the problem.
