avformat/webpenc: don't assume animated webp streams will have more than one packet
The libwebp_animencoder returns a single packet with the entire animated
stream, as that's what the external library produces. As such, only ensure the
stream was produced by said encoder (or propagated by a demuxer, once support
is added) when attempting to write the requested loop value.
Fixes ticket #9179.
