* Make the methods of `CThreadInterrupt` virtual and store a pointer to it in `CConnman`, thus making it possible to override with a mocked instance. * Initialize `CConnman::m_interrupt_net` from the constructor, making it possible for callers to supply mocked version. * Introduce `FuzzedThreadInterrupt` and `ConsumeThreadInterrupt()` and use them in `src/test/fuzz/connman.cpp` and `src/test/fuzz/i2p.cpp`. This improves the CPU utilization of the `connman` fuzz test. As a nice side effect, the `std::shared_ptr` used for `CConnman::m_interrupt_net` resolves the possible lifetime issues with it (see the removed comment for that variable).
