bootutil: fix edge case when not validating slot 0

When not validating slot 0, we could be booting into an empty
chip. This means we jump based on garbage data.

Try to make this better by at least checking the magic number. Without
this patch, booting with just the bootloader fails the Zephyr release
tests.
