Charset filter: fixed charset setting on encoded replies.

If response is gzipped we can't recode response, but in case it's not
needed we still can add charset to Content-Type.

The r->ignore_content_encoding is dropped accordingly, charset with gzip_static
now properly works without any special flags.
