Range filter: clearing of pre-existing Content-Range headers.
Some servers might emit Content-Range header on 200 responses, and this
does not seem to contradict RFC 9110: as per RFC 9110, the Content-Range
header has no meaning for status codes other than 206 and 416. Previously
this resulted in duplicate Content-Range headers in nginx responses handled
by the range filter. Fix is to clear pre-existing headers.
