MYNEWT-518 boot - Allow test+confirm as single act

Currently, to permanently run the alternate image, the boot loader
requires the following sequence:

1. image test <slot-01-hash>
2. reboot
3. image confirm

The new feature is to remove the need for the third step. The user
should be able to permanently switch images with this sequence:

1. image confirm <slot-01-hash>
2. reboot
