xor/kunit: add a benchmark
Add a benchmark to test the XOR functions for more representative block
sizes and numbers of disks. Including 64k would be useful here, but
increasing the test buffer size increases the runtime of the functional
kunit test too much unfortunately.
The runtime numbers are reported in GB/s as the numbers of modern
implementations are basically unreadable as MB/s. This means
retro-architectures could report 0, but that is an easy tradeoff.
