Redundant `toIfaceIdDetails` log

[soulomoon]

e.g.

Loading linkables:                                                 OK (1.02s)
toIfaceIdDetails [ClassOp]
toIfaceIdDetails [DataConWrapper]
toIfaceIdDetails [DataConWrapper]
toIfaceIdDetails [DataConWrapper]

Is pretty annoying

I think this is a regression introduced by #4480 🙈

😂on the good side, it reminded us to use the upstream fat interface api for core bindings.
