block_meta: also add recovery key if zkey is used
When zkey is properly setup, we do not invoke cryptsetup luksFormat
ourselves. Instead we lean on zkey to invoke cryptsetup luksFormat for
us.
zkey seems to have no native support for invoking cryptsetup luksAddKey,
so we need to manually call it if we want to add a recovery key in a
second slot.
