Yeah, I forgot that we don't have this register until gen6 (iirc). We just need to skip this test before gen6.

    i915/gem_ctx_engines: Skip trying to read a non-existent TIMESTAMP
    
    The per-engine TIMESTAMP (at least at the offset I know about) only came
    into being with gen6. So skip the test on older gen as the results are
    garbage.
