ipq40xx: fix sysupgrade image for Netgear LBR20

This fixes the sysupgrade image generation for the LBR20 as before
updating resulted in a brick which needed to be recovered using
nmrpflash.

UART log of a bricked unit:
Loading DNI firmware for checking...
Loading firmware 1 ...

NAND read: device 0 offset 0xa600000, size 0x20000

Comparing the partition contents of a bricked and a working unit showed
that on the bricked one the fake uImage header was missing. The UBI
partition also showed significant changes. Both are fixed when the
base DniImage receipt is used.
