build_image: fix verity defaults

Browse Source 
This changes defaults failure to a panic/recovery reboot and
disables the debugging max_bios argument to ensure that we don't
trigger race conditions in the kernel during un-protected
pending_bio count decrements.  (Can lead to a hung-system.)

TEST=built x86-generic; ensured -1 and the panic changes worked
