QDtls and QDtlsClientVerifier - add destructors

While these destructors are essentially trivial and contain no code,
the classes inherit QObject and thus have virtual tables. For such
classes -Wweak-vtable generates a warning: "'Class' has no out-of-line
virtual method definitions; its vtable will be emitted in every translation
unit." Noticed this after updating QtCreator to the latest version.
