DirEntry contains a ReadDir handle, which used to just be a wrapper
on Arc<InnerReadDir>. Commit af75314 added end_of_stream: bool
which is not needed by DirEntry, but adds 8 bytes after padding. We
can let DirEntry have an Arc<InnerReadDir> directly to avoid that.

unix/vxworks: make DirEntry slightly smaller

`DirEntry` contains a `ReadDir` handle, which used to just be a wrapper
on `Arc<InnerReadDir>`. Commit af75314 added `end_of_stream: bool`
which is not needed by `DirEntry`, but adds 8 bytes after padding. We
can let `DirEntry` have an `Arc<InnerReadDir>` directly to avoid that.

remove ReadDir.end_of_stream on targets that don't use it

Well that's annoying -- that end_of_stream has always been unused in practice on some targets, but the derive(Clone) that I removed was counting as a use. I've added more conditionals, but I'll pause for re-review just in case.
