SkCrabbyAvif: Remove explicit brand sniffing in IsAvif
This code was copied over from SkAvifCodec. While libavif fails
to parse truncated ftyp boxes, CrabbyAvif can detect truncated
ftyp boxes in a best effort basis. So that is superior to the
explicit substring sniffing we do in this wrapper. Remove the
code and rely on CrabbyAvif's sniffing instead.
