Prefer using override instead of virtual in qdbusxml2cpp

In C++ 11 override keyword was introduced to allow overridden functions
to be marked appropriately. Its presence allows compilers to verify that
an overridden function correctly overrides a base class implementation.
This can be useful as compilers can generate a compile time error when:
- The base class implementation function signature changes.
- The user has not created the override with the correct signature.

This commit improves the D-Bus interface code generation.
