update_engine: Deprecate minor version 1

Minor version 1 was for the old days where we rewrite the signle
partition with an update (no A/B partitions). But those days are long
over and we don't think there is any device out that has this capability
anymore. Even if there is, we can always serve full payloads along with
the stepping stone we have in M53. So this is safe to go.

BUG=chromium:1008553
TEST=sudo FEATURES=test emerge update_engine
TEST=ran cros flash two times.
