Backport upstream patch
  https://github.com/glmark2/glmark2/commit/3137e5c184581c9a69c687ecf46ba08f02c4117b
to remove uses of deprecated std::auto_ptr.

commit 3137e5c184581c9a69c687ecf46ba08f02c4117b
Author: Alexandre Courbot <acourbot@nvidia.com>

    Do not use deprecated std::auto_ptr
    
    auto_ptr has been deprecated in recent C++ revisions. As glmark2 is
    compiled with -Werror by default, this results in compilation failures
    with recent g++ versions, e.g:
    
    ../src/model.cpp:684:16: error: ‘template<class> class std::auto_ptr’ is deprecated [-Werror=deprecated-declarations]
    
    Replace the use of auto_ptr with unique_ptr throughout the code to fix
    this.
