app: aboot: pass the a/b slot specific information in verity bootparam
On LE, When A/B and verity are enabled together the kernel command line
should be formed such that the verity boot-param clearly indicates the
system partition name and the corresponding block device, as follows:
...androidboot.slot_suffix=<slot_suffix> ...rootfstype=ext4...
...root=/dev/dm-0 dm="system_<slot_suffix> none ro,0 1 android-verity
dev/mmcblk0p<NN>"
where:
slot_suffix: indicates the identified slot to boot from
dev/mmcblk0p<NN>: <NN> indicates the corresponding blockdevice
