[libcxx-commits] [libcxx] [libcxx] Switch to check-runtimes for generic-llvm-libc (PR #196780)

[Aiden Grossman via libcxx-commits]

After a1d21ccf78e7893134c8c8cccd78e7d7d545a9c3 we have a dl_iterate_phdr implementation sufficiently complete to run the libunwind tests, so now we can remove the hacky to avoid testing libunwind and just use the generic check-runtimes function.
