selftests: ublk: track created devices for per-test cleanup

Browse Source 
Track device IDs in UBLK_DEVS array when created. Update
_cleanup_test() to only delete devices created by this test
instead of using 'del -a' which removes all devices.

This prepares for running tests concurrently where each test
should only clean up its own devices.
