nwztools: rework dualboot

The new code gets closer to an actual bootloader:
- it provides a menu with three options: Sony, Rockox, tools with icons (and
  extracts the Sony logo from the NVP)
- the dualboot install script now creates a symlink from /.rockbox to
  /contents/.rockox which is necessary to run rockbox
- more text drawing / framebuffer functions
In the long run, we will move this under bootloader/ and rbutil/ and also use
firmware/ drawing facilities, at the moment we use OF display program which
is slow and creates some flickering.
The logo extraction/placement code was tested with resolution 240x320 and I
guessed some reasonable values for 240x400, but those will probably need some
tweaking.
