chore: exclude e2e tests from make test unconditionally

The `test/cvo` e2e tests require a live OCP cluster and were
excluded from make test only when CI=true. This caused make test
to fail locally when no cluster is available.
This commit makes the exclusion unconditional so make test
behaves consistently
