selftests: ublk: add end-to-end integrity test

Browse source

Add test case loop_08 to verify the ublk integrity data flow. It uses
the kublk loop target to create a ublk device with integrity on top of
backing data and integrity files. It then writes to the whole device
with fio configured to generate integrity data. Then it reads back the
whole device with fio configured to verify the integrity data.
It also verifies that injected guard, reftag, and apptag corruptions are
correctly detected.
