tests/fate/libavutil: add FATE test for dovi_meta

Browse Source 
Test av_dovi_alloc, av_dovi_metadata_alloc, and av_dovi_find_level.
Verifies that the four inline offset-based accessors (get_header,
get_mapping, get_color, get_ext) return pointers consistent with
the offset fields, that find_level returns the first matching ext
block or NULL for a missing level, and OOM paths via av_max_alloc.
