[cxx-interop] Adjust a concepts test for rebranch

Clang now includes concepts in the mangled names of C++ functions: swiftlang/llvm-project@4b163e3

This adjusts the test to verify that we don't transitively emit the symbols referenced from the requires expression. Those symbols shouldn't be emitted because they are not executed.
