Inspired by U-Boot's addition of the ufetch command and the neofetch
utility for Linux[1], add a similar command to barebox.
The command is meant to simplify showing off a barebox port with some
colored ASCII art. The usual alternative is a screenshot of a barebox
boot up and prompt, which for a fresh port usually will contain some
>= warning messages, which is not as pleasant to look at compared to:
