Amaury Pouly d492f25c54 nwztools: add preliminary dualboot and dualboot install script
At the moment, the script install_duaboot does the following:
- rename SpiderApp to SpiderApp.of (unless it already exists)
- install payload as SpiderApp
- fixes permissions
Since SpiderApp is the main app, it will execute instead of the OF.
The current dualboot code (dualboot.c) is still a preliminary but the current
version displays an "all tools" menu to choose for. When exitting the menu
using BACK, it will run the OF.

With the modifications made by the install script, it should not be possible
to break the device. In the worst case scenario, the dualboot code crashes
and it restarted by the sysmgrd, or hangs. A safe way to recover is to plug
the USB cable and reset the device: the system manager will then start the
USB app and one can reflash the device if necessary.
