ext/vorbis/vorbisenc.c: Remove leaks from vorbisenc.

Browse source 
Original commit message from CVS:
* ext/vorbis/vorbisenc.c: (gst_vorbis_enc_set_header_on_caps),
(gst_vorbis_enc_chain):
Remove leaks from vorbisenc.
Mostly minor changes, the only significant one is that now the
buffers we set as 'streamheader' on the caps are copies of the
original buffers, to avoid circular refcounting problems.
