hdiffpatch: add build-hdiffpatch.yml for riscv64 wheels
Adds a cibuildwheel-based riscv64 build for hdiffpatch 2.6.0, mirroring upstream's own build_wheels.yaml linux job. Stages the vendored third-party codec licences (zstd, tinyuz, brotli, lzham_codec, tamp, bzip2, zlib, lz4, libdeflate, libmd5, lzma) at the project root so the default license-files glob picks them up, since upstream's own wheel ships only its wrapper LICENSE.
