chainloader needs to pass boot device to LoadImage()

[Trammell Hudson]

The Windows bootloader uses the devicepath argument to LoadImage() to determine which device it is booting from. We need to ensure that it receives the correct one.

It is currently passed as an int, perhaps having an ioctl or sysfs file to retrieve it would be better, which chainload could query based on the exe to be run.
