refactor(debos): drop qbootctl

qbootctl marks the current Android boot partition as successfully
booted, which the Android bootloader needs so it doesn't fall back to
the other slot after a few boots. This was only required on RB1 where
the Android bootloader chainloaded U-Boot from the boot_a/boot_b
partitions.

As RB1 now boots through the EDK2 bootflow, no supported board depends
on this slot handling any more so drop the package.
