feat(nix-compat/wire/bytes/reader): split out reading the trailer block r/8016

We separate ingesting the trailer block into a Future of its own,
parametrised on the specifics of the trailer pattern.

This is intended to be used for future work on an async NAR reader,
which needs to read a terminating parenthesis as well as the regular
padding.

Thanks to @griff for suggesting separating the ingestion into its own
Future.
