[PATCH] gpu: nova-core: fix warning with NOVA_CORE_SELFTESTS disabled

[Alexandre Courbot]

A module-wide new import becomes unused if the `NOVA_CORE_SELFTESTS`
config option is disabled:

    warning: unused import: `Spec`
      --> ../drivers/gpu/nova-core/driver.rs:29:9
       |
    29 |         Spec, //
       |         ^^^^
       |

Fix this by fully qualifying the unique use of `Spec` when the tests are
enabled.
