This change looks for clang-format (and its script) *also* inside third_party/clang-format (on top of buildtools/$plat). This is to bring consistency to the recent changes [1] to gn and ninja wrappers, which now look only in third_party and not in buildtools/. This is to make it so that a project can use depot_tools without requiring both buildtools/ and third_party/ directories.
