Add a logo to the fastbootd screen.

fastbootd looks too much like recovery, even if you're carefully reading
the menu. It's not obvious the device is in a flashing mode, and it's
too tempting to reboot or unplug the device in this state.

As a first step, this patch adds a big red "fastbootd" logo so it's less
obviously in recovery mode.
