Sebastian Dröge dcea8baa14 avcodecmap: Don't try converting channel layouts with more than 64 channels
We only support up to 64 channels in GStreamer with a specific layout so
it's safe to assume a NONE layout in this case.

Also the arrays of channel positions are allocated everywhere with 64
elements so don't try setting more than 64 to NONE as that will cause
stack corruptions and similar memory safety issues.

Thanks to Natalie Silvanovich for reporting this issue.
