zluda: remove redundant cargoHash

[alyssais]

Only one of cargoHash and cargoLock needs to be specified. cargoLock takes precedence over cargoHash, so removing this should be a non-functional change, despite the rebuild.

Is there a specific reason we are vendoring the lockFile here? fetchCargoVendor doesn't work here?

[alyssais]

It might do, but I don't know, so I want to leave things as they are, and just clean up the unused attribute.

[JohnRTitor]

Right apparently upstream doesn't even vendor Cargo.lock.
