releasetools: Only verify the blocks to be touched.

For incremental BBOTAs, we used to verify the integrity of all the
blocks in the source partition. In order to reduce the time cost under
recovery, this CL changes to only verify the blocks that will be touched
in the given OTA package (BBOTA >= 3 only). This is a trade-off between
performance and reliability.
