[llvm] [JITLINK] Disable ELF_ppc64_relocations.s on SystemZ host (PR #168939)

[via llvm-commits]

https://github.com/anoopkg6 created https://github.com/llvm/llvm-project/pull/168939

Mark ELF_ppc64_relocations.s as unsupported on SystemZ because of cross build issue related to using dlsym for host symbols.
Test fails to resolve __tls_get_aadr on SystemZ host.
