gst-plugins-base1: disable sndio by default

upstream has noted that this patch is problematic and actually
breaks things for people who don't have sndio installed, plus
the patch is not present anywhere in upstream and it is outside
the distro policy to patch features in

therefore, disable by default at very least, and add a note

in longer term this should either be split off, upstreamed
or removed if it cannot be upstreamed
