[Intel-gfx] [PATCH i-g-t 4/4] lib/i915: Pick a subtest conformant name for an unknown engine

[Chris Wilson]

IGT disallows ':' in its subtest names, and as we use the engine name
for dynamic subtest names, pick a name that doesn't accidentally cause
IGT to assert (even when those tests are not being run).
