httpd_output: save the page generated by encoder_tag()

Flush the encoder before calling encoder_tag(). The first page generated by the encoder after sending the tag will be the new "header" page, which is sent to all HTTP clients when they connect. This is a little bit specific to the vorbis encoder, but there are no other encoders which support tags (yet).
