Check super size for factory OTA at build time

For VAB launched device, factory OTA will write system_other
partition to the super image. So we want to check that
sum(dynamic partitions) + system_other + overhead <= super at
build time.

Since we don't know the overhead at build time, we might instead
check sum(all partitions) < super.
