Title: headers: strip accept-bytes and vary-accept-encoding

If we're proxying the origin server might advertise `Accept-Ranges: bytes` but
we don't support range requests. So we need to remove the header. We also need
to not add `Vary: Accept-Encoding` twice, and because the gzip encoding will add
it later we need to remove it here.
