This adds two new logging macros, which are intended to be async signal safe: * `SANDBOX_LOG_ERRNO`, which appends the error similarly to `perror` but uses the error identifier (e.g., `EINVAL` instead of `Invalid argument`). Unlike `perror`, formatting directives are available as for `SANDBOX_LOG`. * `SANDBOX_LOG_WITH_ERROR` is the same thing but the error number is the first argument instead of using `errno`; this is useful for newer POSIX APIs which return an error number. This will be used in the next patch to replace the existing use of `strerror`, which is not async signal safe (or thread-safe). Differential Revision: https://phabricator.services.mozilla.com/D152098
