[Buildroot] [PATCH] board/broadcom/northstar: fix building custom images

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

Custom Northstar images allow installing (flashing) them using vendor UI
or CFE bootloader. Change of DTS files paths ("broadcom/" prefix
introduction) prevented post script from generating them.

Adjust post-image.sh to deal with new paths.
