Revert "[K/N][test] Use ld classic for XCTest-based tests"

The new Apple linker failed with SIGBUS when linking XCTest-based tests.
After fixing KT-74764, this is no longer the case. See the detailed
explanation in the issue: ^KT-70202

Therefore, the workaround of using the ld classic in that case is no
longer required.

This reverts commit 7f1008ef917dfe8cc23125184582976a4bdf361e.
