fix(nix-compat/wire/bytes/reader): always read trailer tag data r/8085
Even if we have an aligned (or zero) size (and thus have no padding),
we may still have a non-padding trailer.

Since an exact read of only the user data bytes must always read the
trailer bytes as well, this has to happen for aligned sizes too.

For zero-sized trailers, we solve this by reading immediately, since no
read is required of the user at all.

user_len thus becomes a NonZeroU64, and the definition of "body data"
is adjusted to always exclude the final block.
