The unit test container runs with Docker default seccomp
profile which blocks io_uring_setup, io_uring_enter and
io_uring_register. This causes all qcow_async unit tests to
fail with EPERM when creating an io_uring instance.
Add --security-opt seccomp=unconfined to the unit test docker
run invocation. The container already has --device access and
cap_net_admin, so this does not materially change the security
posture.
