harfbuzz: fix CVE-2022-33068

Backport patch from
https://github.com/harfbuzz/harfbuzz/commit/62e803b36173fd096d7ad460dd1d1db9be542593

The 'tff' file in upstream patch is for testing only which cause error during do_patch so need be dropped.
File test/fuzzing/fonts/sbix-extents.ttf: git binary diffs are not supported.
