MDEV-19908: Add override keywords
Fix the build on clang. GCC only checks that a member function with the C++11 override keyword is actually overriding a virtual member function in a base class. In clang, you will get a warning for overridden member functions that lack the keyword, if any overridden member function of the class is declared with the keyword.
