[google-sargo] Boot fails due to missing FW files

I've built locally SSH-enabled sdm670 image, flashed it on top of already existing Mobian system (that needed manual tweaks as well to workaround this issue) and boot blocks with Mobian's "Extracting firmware" splash screen.

Killing droid-juicer gets the "Extracting firmware" splash screen away, but screen stays black. AFAIK, a615_zap.* FW files are required for video to work.

@a-wai already pointed out, Android partitions as flashed by recent Google images are broken, therefore droid-juicer fails to collect FW files. And without FW files, Mobian fails to start...

Google's flashing script for latest factory image is broken, and I had to go through lots of manual commands to fix my own sargo, which is why I do believe it should be upgraded to latest from within Android; otherwise the partition scheme will likely be broken wrt. droid-juicer's expectations and Mobian won't work well
