wrappers: Stop specifying -fuse-cxa-atexit

Since clang 9.0.0 (34ec6929a1fb33716d0035dc0f1f164d7568b4dc in llvm-project), it's no longer necessary to set this to be able to use __cxa_thread_atexit (for TLS destructors). This brings the behaviour closer to GCC, and reduces the amount of non-default options used.
