__builtin_os_log_format is implemented by Clang, not a library, and is quite involved. Implementing os_log in an overlay to provide near feature-compatibility with the C API is the right approach for Swift 3, where a more comprehensive solution (say, a general logging API based on string interpolation or similar) is way out of scope.
