Fix flatbuf sandboxing build

2024-10-04T07:09:17Z

Fix for sandboxing builds like https://a.yandex-team.ru/ci-card-preview/23700000012721 (2nd iteration of https://a.yandex-team.ru/review/6927716/details) Explanation is here https://docs.yandex-team.ru/ya-make/manual/common/macros#induced_deps, the flatbuf command currently emits .cpp in addition to .h (this is need for immediate schema validation by `ya make my/flatfbuf/schemas` build. The headers alone won't trigger any build and so code generation) commit_hash:f27ec4e20e6fd552df2934802a4a6251893bc53a
