feat(netwatch, portmapper)!: switch from thiserror to snafu

## Description
Try to switch from thiserror to snafu.
## Breaking Changes
Error variants changed shape a bit, generally use `#[non_exhaustive]`
and contain a named `source: OtherError` field instead of wrapping an
unnamed `OtherError`, and in addition have a `backtrace:
Option<snafu::Backtrace>`.

## Change checklist
- [x] Self-review.
