[WebAssembly] Update ADT/TripleTest.cpp now that default file format has changed

Summary

See: https://reviews.llvm.org/rL323220

The new tests look good, but it'd be good to keep testing "wasm32-unknown-unknown-wasm" and "wasm64-unknown-unknown-wasm" here too.

Please restore the "-wasm" forms of these tests too.

I've now re-added these tests myself, in r325273.

Sorry about that. You are right to test all the cases.
