mod_brotli, mod_deflate: Restore the separate handling of 304 Not Modified

responses allowing these modules to properly set or fix-up the response

headers such as Vary or ETag.

This change follows up on r1837056 that disabled that special handling and

thus resulted in a potential violation of RFC7232, 4.1:

  The server generating a 304 response MUST generate any of the following

  header fields that would have been sent in a 200 (OK) response to the

  same request: Cache-Control, Content-Location, Date, ETag, Expires,

  and Vary.)
