Subject: [PATCH 6/7] lib: Give XOR_BLOCKS, RAID6_PQ config opts names

Give these config options names so that they show up under the "Library
routes" kernel configuration menu, and can be enabled by distributions.

These are needed for bcachefs to be built out of tree.

These libraries are both for RAID5/6.
