Summary: D31464478 enabled clang-format by default across projects, but opted out directories with a lot of formatting errors. This removes the opt-out, so clang-format is run in that directory as well. Changelog: [Internal][Changed] - Remove clang-format opt-out for Libraries Reviewed By: lunaleaps Differential Revision: D40310275 fbshipit-source-id: abe154ab466798fbfa010364a3627f40ca18b179
