There is no such thing as MPEG4 WebM.

> +FATE_AV1_FFMPEG_FFPROBE-$(call TRANSCODE, LIBAOM_AV1 MPEG4, WEBM IVF) += fate-libaom-write-hdr10-plus
> +fate-libaom-write-hdr10-plus: CMD = transcode webm $(TARGET_SAMPLES)/mkv/hdr10_plus_vp9_sample.webm ivf "-map 0 -c:v libaom-av1 -cpu-used 8" "" "-show_frames -show_entries frame=side_data_list"

This test includes a checksum of the generated file. The test will
therefore fail as soon as libaom-av1's output changes. Use enc_external
instead.

This test has the same issue as the above; if ffprobe were changed so
that one can force a specific decoder, this whole test could be made
redundant by using the libaom-av1 decoder with ffprobe in the test above.
