gst-plugins-base: use upstream fix for ivorbis plugin build fail
Previously, I submitted a patch "[PATCH v2][packages]gst-plugins-base: disable building ivorbis plugin" that disables ivorbis plugin build. Michel Stempin pointed out an upstream patch that fixes the issue directly in the vorbis decoder header. I had missed this patch in my previous searches.
This patch reverts the disabling of ivorbis and adds the upstream fix. I have tested this patch and it fixes the build issue. Thanks to Michel Stempin for bringing this to my attention and pointing me to the upstream fix.
