Mark PatternTreeParser::Node destructor as virtual
The non-virtual base-destructor causes its derivate classes to leak tiny bits of memory otherwise. The header is private and not to be used outside of APT, so we can perform this tiny ABI break as there is no ABI to break. Reported-By: valgrind and clang -fsanitize=leak
