From: Philippe Mathieu-Daudé <philmd@linaro.org>

sprintf() is deprecated on Darwin since macOS 13.0 / XCode 14.1.
Using qemu_hexdump_line both fixes the deprecation warning and
simplifies the code base.

Note that this drops the "0x" prefix to every byte, which should
be of no consequence to tracing.
