oggmux doesn't ever set EOS on the pages it should.

As well as being out of spec in a minor way, this causes at least one very
serious practical problem:

Vorbis treats BOS/EOS specially, in order to clip the start/end of the stream
to the correct length (so that your encoded file can be decoded to something
exactly the same length as the original data). If the EOS flag isn't there, it
doesn't (can't) know to do this.

Result: ... ! vorbisenc ! oggmux ! filesink produces an output file that
decodes more data than it's meant to, some of which has just been invented by
the encoder.
