Can this go in max_path_len_tests.rs?

Could do...Generally we haven't shied away from doing unit tests in the same module that we're testing, at least for modules that aren't 10k LoC already 😅...

Tagging this 0.1 since it currently causes some of the Java bindings tests to fail, so its easier if we get it in before the release. |
When either the amount or the `max_total_cltv_expiry_delta` are set to max-value, `set_max_path_length` can trigger overflows in `build_onion_payloads_callback`, leading to debug-panics.
