restructure Poll to hold a Table and fd instead of a RefMut<dyn WasiFile>
...
unfortunately, the borrow checker defeated me: changing the
RwSubscription file form a Ref to a RefMut turned into borrow checker
errors in the impl of the poll_oneoff trait method.
This implementation makes an end run by having Poll hold onto the table
and fd, and borrow the file at the site of use, rather than try to own
the RefMut. I have no idea why this convinces the borrow checker that
anything is different, but it does and I need to get this PR done and
I don't think comprimising on this internal abstraction is worth
fighting against

Support "sleep" forms of poll_oneoff.
...
Add support for `poll_oneoff` calls which just sleep on a relative
timeout. This fixes a bug handling code compiled with WASI libc's `sleep`
family of functions, which call `poll_oneoff` with a `CLOCK_REALTIME`
timer, which wasn't previously implemented.

Use min_by instead of sort_by when we only want the minimum element.

This is just a minor code simplification I happened to notice while
doing unrelated work on `poll_oneoff`.
