When concatenating the strings to form a new command line in the
android bootloader flow, the null-terminator was placed one byte after
the end of the allocated string.

The android_bootloader_control struct defined in bootloader_message.h
stored the A/B metadata used to decide which slot should we use to boot
the device. This patch implements the bootloader side of the slot
selection in a new "android_ab_select" command which decides the
current slot and updates the metadata as needed.
Bug: 32707546
Test: Booted a rpi3, updated to the other slot.
