[DistroKit] [PATCH 5/8] barebox: enable bootloader dm-verity support

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

To make it easier to evaluate this new feature, enable it in in the
barebox config, even if we do not make use of it yet.

Compared to FIT images, the benefit of dm-verity directly in barebox
would be that we do not need to change our current partitioning and can
continue to place the kernel, device tree and initrd into a file system
and arguable reducing the attack surface at the same time, because the
block-sized hashing is simpler than the FIT image parsing.

It would also be more straight forward to optimize for boot time, as
barebox could do better prefetching, albeit that's not yet implemented.
