httpd: When sending gzipped content use content-length header

Today for gzipped content httpd is using a header with name
Transfer-Length. However I can't find a header with that name in the
standards. Instead use Content-Length.

.rodata                                           157940  157936      -4
send_headers                                         980     939     -41
