Tim Armstrong resolved IMPALA-5391.
-----------------------------------
       Resolution: Fixed
    Fix Version/s: Impala 2.9.0



IMPALA-5391: remove C++11 from UDF header

This replaces the C++11 idiom with equivalent C++98 code. The code was
added to address a clang-tidy warning about missing virtual
destructors, which the new code should also address.

> uda-test-harness.h doesn't compile with older versions of GCC. This is unhelpful when trying to build Impala UDFs using the native compilers on older OS versions.
